PS: Writing the game in one go, there should be more than 10,000 words, not to be missed!

——

"Congratulations to Imperial College London for being the first to solve [Question B] in 11 minutes and 09 seconds!"

With the announcement of the competition committee, a balloon with the sign "FIRST-PROBLEM-SOLVED" was raised behind the area where the three players of the Imperial College London team were located.

This is the honor of the team that solves each problem first.

When he heard that it was Imperial College London, Huang Youjie was slightly disappointed, and he thought that it might be Abin and they solved [Question B].

"Imperial College London is very strong, there is no doubt about it, it took 11 minutes and 09 seconds, which is very powerful. Ding Yue couldn't help frowning.

If this trend continues, will his Fog City University of Arts and Sciences not be able to compete for the final championship?

The format of the ACM competition is to calculate all the accumulated time of answering questions, and the shorter the answering time, the more chances of winning the championship.

If there is still the last question left, the time gap between many colleges and universities is only a few minutes, and when it takes more than ten minutes, there is a chance to catch it back with the last question.

Even if there is a difference of more than 20 minutes or half an hour, there is hope.

I'm afraid that those colleges and universities with perverted strength will solve the first few questions in about ten minutes, so they will be more and more distant from other universities.

Backbite!

"Foggy City University of Arts and Sciences successfully passed [Question B] in 11 minutes and 26 seconds!"

The sudden sound of the competition committee's announcement suddenly made Ding Yue feel uplifted!

Very own Fog City University of Arts and Sciences!

It was actually the second college team to solve [Question B], which made Ding Yue feel a little surprised.

The first question is ranked higher in time, and this second question is directly second, and the difference with Imperial College London, which was the first to solve [Question B], is only 17 seconds, which is not a gap at all.

"Brother Yue, Abin, they're awesome! You solved this problem so quickly?" Huang Youjie excitedly grabbed Ding Yue's arm after hearing the briefing of the competition committee.

"Hahaha, it seems that Abin really didn't disappoint me, and Chen Jun and Ouyang Chen are not bad. ”

With such good results, Ding Yue was naturally happy in his heart.

If you combine the time taken by the first and second questions, I'm afraid that Fog City University of Arts and Sciences can be among the best, right?

Then St. Petersburg State University, California Polytechnic University, Nanyang Technological University, Haicheng Jiaotong University, Moscow State University and other universities also passed [Question B], and the time used by everyone is actually about the same, at most a time interval of one or two minutes.

These are all first-tier participating universities, and their strength is strong in all aspects.

As an opponent, you have to pay attention to it.

Subsequently, more than a dozen other universities also passed [Question B], including Northwestern University of Science and Technology from Xia Kingdom.

This time, the University of Cape Town in Africa is not the only university that has failed in [Question B], and there are three other universities that have solved [Question B].

In the end, 30 minutes of time passed, and the four universities were not able to get the results.

As a result, the University of Cape Town, from Africa, completely lost the opportunity to compete for the ACM title.

Then the other 30 or so universities are currently divided into two echelons, the first echelon is St. Petersburg State University, Imperial College London, California Polytechnic University, University of California, Berkeley, Haicheng Jiaotong University and other strong universities.

Of course, Ding Yue's Wucheng University of Arts and Sciences is also in the first echelon, and his current scores are in the forefront of the first echelon after answering the two questions.

This question is more difficult than the first question, and the competition becomes exciting from the beginning of [Question C].

Because when the competition committee released the third question, the participating teams from all colleges and universities were in full swing to answer the questions.

This time, no university solved [Question C] in about ten minutes, and the most important thing is that the time given by the competition committee for this question is actually 45 minutes.

The time taken to solve a question has increased, which also means that the difficulty of the question has increased dramatically.

A university like the University of Cape Town, which is not very strong, was a little overwhelmed when it came to [Question C].

"There doesn't seem to be a way to solve this program!"

"No way, is there a question that the competition committee will issue that cannot be solved? ”

"Can you try to solve it in C?"

"Even, it's too difficult, or it's impossible. ”

The participating teams from several colleges and universities with relatively low grades were suddenly stumped by this [Question C], which was like a roadblock.

Through this question, the teams with strong computer skills were completely distinguished from the teams that were not very good at computers.

The college teams in the first echelon did not show any difficulty when facing this problem, and everyone was solving the procedure in an orderly manner.

With the strong assistance of his two teammates, Xu Bin is also comfortable in programming and writing.

This problem is indeed very difficult, but for a computer genius like Xu Bin, such difficulty is nothing more than the process of writing a program that is a little more complicated, not an unsolvable program problem.

Like Xu Bin and others, the players of several other first-tier university teams are calmly programming to solve this problem.

The second-echelon college team players, some of whom performed well, treated them as calmly as the first-echelon universities.

And some of them began to discuss with the three of them.

Discussion means that they don't have the idea to solve the problem in the first place, which is a waste of time.

After all, the ACM International Collegiate Programming Competition is about who can solve the program problems given by the competition committee faster and more efficiently.

Twenty minutes passed.

It's still quiet on the field, and there is no first college team to solve [Question C].

Even Ding Yue couldn't help but hold his breath, wondering in his heart if this question was so difficult?

Basically, after ten minutes of the first two questions, colleges and universities began to solve them one after another, and now this question, twenty minutes later, there is still no movement.

[Live Room of Science and Education Channel of National Television Station]——

"I'm a computer science major, and with all due respect, I'm dumbfounded by this question. ”

"Twenty minutes, right? Still no team has solved this problem?"

"It's so difficult, Ako. ”

"This question should be a good opportunity to chase scores, Haicheng Jiaotong University!"

"Kirijo University of Arts and Sciences!"

"Northwestern University of Science and Technology to Ye Chong!"

"It's over, the third question of the ACM competition, I basically can't understand it as a computer student. ”

"It's really difficult, and it's very complicated to solve. ”

"Yes, yes, yes, not only is it complicated, but if you are not careful, there will be a program error, which is very difficult. ”

In the live broadcast room of the science and education channel of the national television station, more than 20,000 viewers are from Wucheng University of Arts and Sciences.

This ACM International Collegiate Programming Competition is important for Fog City University of Arts and Sciences.

Because this is the first international competition of Fog City University of Arts and Sciences, many students of Fog City University of Arts and Sciences have spontaneously paid attention to the competition.

Backbite!

The scene of the competition.

Finally, the voice that everyone was familiar with sounded.

"Congratulations to Moscow State University for successfully solving [Question C] in 23 minutes and 41 seconds!"

Bang!

With the announcement of the competition committee, an orange balloon with the sign "FIRST-PROBLEM-SOLVED" was raised behind the three Moscow State University contestants.

In fact, the color of each balloon is different.

"It seems that the time required for each of the following questions should be more and more. Ding Yue couldn't help but sigh with emotion after seeing that Moscow State University had successfully won the first place in this question.

The time taken for this question is almost double that of the previous one.

"Moscow State University is very strong, and in recent years it has almost won the championship of the ACM competition with St. Petersburg State University!"

Huang Youjie said with his mobile phone in his hand.

He had just checked the information and found out that Moscow State University and St. Petersburg State University had won a lot of championships in ACM competitions in recent years.

"I just want to know when Abin and they will solve this problem!"

Ding Yue's expression became a little solemn.

If each of these questions takes a long time, then the later variables may be larger.

For example, St. Petersburg State University, which passed the first question first, has not yet solved this problem.

Backbite!

"Haicheng Jiaotong University successfully passed [Question C] in 24 minutes and 07 seconds!"

The second one to solve [Question C] is actually Haicheng Jiaotong University.

It seems to be the most promising university in China, with extraordinary strength, and even has the opportunity to compete for the championship.

Backbite!

"Imperial College London successfully passed [Question C] in 24 minutes and 29 seconds!"

Backbite!

"Fog City University of Arts and Sciences successfully passed [Question C] in 24 minutes and 33 seconds!"

Soon, suddenly, two universities in a row solved the problem in less than five seconds.

And one of them is Ding Yue's Fog City University of Arts and Sciences, which is almost better than Imperial College London's score on this topic.

"The gap is not big, the gap is not big, it's okay!" Ding Yue breathed a sigh of relief for the time after hearing that his time score for the question of Wucheng University of Arts and Sciences came out.

The difference between the first place and the first place is only a minute, and this minute does not have a big impact in the later questions.

"President Ding, our Wucheng University of Arts and Sciences has scored well in these three questions, and it seems that our results are not bad. ”

Wen Ruohan said happily.

"Well, I can only say it's okay. Ding Yue glanced at Wen Ruohan, who was very excited, and said: "I have to stabilize it until the end of the game, and then other colleges and universities will rise and fall, in this way, there should be a chance." ”

Ding Yue said that other universities have risen one after another, which means that like St. Petersburg State University, which ranked first in the first question, California Polytechnic University in the second question, and Moscow State University in the third question, although one question was solved first, as long as it was a little slower later, then the time score would be leveled.

On the contrary, like Ding Yue's Wucheng University of Arts and Sciences, the scores of each question are relatively high, and the time gap with the first and second places is not large.

In this way, Ding Yue's time performance of Wucheng University of Arts and Sciences may be a little ahead.

However, the results of St. Petersburg State University have always been relatively good, and California Polytechnic University, like Ding Yue's Fog City University of Arts and Sciences, has never won the first place, but its results have always been at the forefront.

Sometimes it was even better than Ding Yue's Fog City University of Arts and Sciences.

Forty-five minutes passed.

In the end, only 25 colleges and universities passed [Question C], and this obstacle directly stopped nine universities this time, so you can imagine how difficult the next question will be.

"Brother Yue, every question in the back of this will be more difficult, right?" Huang Youjie, who was sitting next to Ding Yue, couldn't help but ask.

"That's for sure, every next question will knock down one university after another, and if one of these questions is not solved, then basically you will not be able to win the championship. ”

Ding Yue nodded and replied.

"Then Abin, they must not make a mistake!" Huang Youjie suddenly became nervous.

This third question has already stumped nine colleges and universities, and Huang Youjie can't be nervous.

Ding Yue calmed Lao Huang's nervousness, and said with a smile: "Lao Huang, let's believe Ah Bin and them." ”

Actually.

Ding Yue said so on his lips, but he didn't have any bottom in his heart, believing is believing, but whether he can clear the customs all the way is indeed an unknown.

When the time comes, won't the sixth and seventh questions be difficult to reach heaven?

With the end of the third question, the competition committee soon opened the fourth question.

After all, the competition lasts for five hours, and although it may be extended for various reasons, you can't waste too much time between each question, because the longer the interval, the easier it is for the contestants to lose the feeling of hot hands and thoughts.

[Question D] appeared.

In the competition area of Wucheng University of Arts and Sciences, Xu Bin sat in front of the computer, and Chen Jun and Ouyang Chen were on his right.

"Director Xu, this is a security vulnerability completion procedure. After analyzing [Question D], Chen Jun said to Director Xu Bin: "It seems to be difficult, we can pass the ......"

If Chen Jun is allowed to solve this problem alone, I am afraid that Chen Jun will not have a bottom in his heart.

But this is a team of three, and with Director Xu Bin in charge, Chen Jun is not so worried.

"Security breaches?"

After hearing Chen Jun's words, Xu Bin couldn't help but look at this question.

The program of security vulnerabilities, Xu Bin likes it the most.

Ever since he started studying computer science at the University of Arts and Sciences in Foggy City, Xu Bin has been working on a security system.

At present, all the basic network equipment in Wucheng University of Arts and Sciences has a security system, which is independently developed and designed by Xu Bin.

Starting from the fourth question, the three contestants of almost all the college teams were discussing for the first time.

That's right!

The first three questionsMany colleges and universities have already begun to write programs to solve bugs as soon as they see the questions.

And the fourth question, if you want to complete it in an efficient way, I am afraid it is not so easy.

"If the first three questions are appetizers, then the fourth question begins, and the real difficulty comes. ”

"It doesn't look like it's a very easy problem to solve. ”

"I have to say that the questions of the ACM competition committee every year are very difficult, and those who can successfully solve seven questions are the top level in the world. ”

Many viewers who love computer programming began to talk about it.

In fact, there are many computer experts in these live audiences, after all, the influence of the ACM competition is still quite large.

However, even if you are a computer expert, when facing the fourth question, you have to sigh that this question is actually quite difficult.

But these computer whizs don't mean that the problem can't be solved.

The solution must be solvable, and it depends on how the participating teams of each university solve it.

"This security breach may seem exaggerated, but it's actually not very difficult. After reading the question, Xu Bin began to fix the security vulnerability.

The fourth question is to allow the participating university teams to fix this security vulnerability through the program.

Since you want to fix this security vulnerability, you must first understand what the programming code of this security vulnerability looks like.

This is the first major hurdle for many universities.

But for a computer genius like Xu Bin who has been exposed to countless security vulnerabilities, this does not seem to be difficult.

Soon, Xu Bin found the programming code of this security vulnerability almost immediately.

Remediation then begins based on security vulnerabilities.

The competition committee gave a full hour of time for this question, which shows that the competition committee has a high evaluation of the difficulty of this question.

"Director Xu, do you know the programming code of this security vulnerability?" Chen Jun couldn't help but ask in surprise when he saw that Director Xu Bin had directly started to fix the security vulnerability.

While others are still analyzing what kind of programming code this security vulnerability is, Director Xu Bin is already on the way to fix it.

This means that Director Xu Bin is a lot ahead of other universities on this question!

"I've been exposed, I've done security systems, I've tried a lot. While fixing the security loopholes, Xu Bin said to Chen Jun: "It's really a coincidence. ”

After Chen Jun heard this, he didn't ask anything more, because if he asked again, it was estimated that it would delay Director Xu Bin's time to fix the security vulnerability.

In this question, the role of Chen Jun and Ouyang Chen has become much smaller all of a sudden, and it basically belongs to Director Xu Bin's personal show.

Ding Yue saw that Xu Bin seemed to have started writing programming code to fix security vulnerabilities in the backstage lounge, and he suddenly felt a little excited.

"It seems that Abin seems to be determined to win this question!" Ding Yue said excitedly.

"Is it? Huh? Abin has already started to fix security vulnerabilities? Contestants from other colleges and universities are still discussing it!"

Huang Youjie also saw the scene of the game through the screen in the lounge.

The 34 university teams can be seen, and most of them, including St. Petersburg State University and Imperial College London, are still discussing how to fix this security vulnerability.

Xu Bin of Wucheng University of Arts and Sciences has already begun to repair, and Chen Jun and Ouyang Chen on the side seem to have completed the task, and everything will be handed over to Xu Bin, who is responsible for programming and repairing security vulnerabilities.

Gradually, more people began to pay attention to the contestants of the Fog City University of Arts and Sciences.

The way they solved this problem seemed to be different from that of other participating universities, and they started to fix the security vulnerabilities without much discussion?

After 27 minutes and 30 seconds, the judging panel of the competition committee received the "answer sheet" submitted by Wucheng University of Arts and Sciences.

"Did you fix this security flaw so quickly?"

One of the judges of the judging group looked at several colleagues around him in surprise and asked.

"Let's take a look at it first, this security vulnerability program, according to previous experience, takes nearly forty minutes. Said another judge of the judging panel.

Then the judges began to score whether the "answer sheet" submitted by Fog City University of Arts and Sciences passed or not.

About three minutes later.

"This ...... The security flaw has really been fixed!"

The judges were all surprised!

[Question D] is the only programming question for security vulnerabilities in the ACM competition, and the difficulty is naturally very high, otherwise it would not be possible to give a full hour of time to answer the question.

In 27 minutes and 30 seconds, the team from Fog City University of Arts and Sciences has successfully solved and fixed this security vulnerability.

For the judges on the judging panel, it was incredible!

"Genius, to be able to fix this security vulnerability so quickly, I have to say, this is a real genius!"

A judge named Smeagol couldn't help but sigh.

"Pass, declare!"

The judges of the judging panel unanimously concluded that the "answer sheet" submitted by Fog City University of Arts and Sciences was indeed a successful fix for the security vulnerability.

Backbite!

Just when the other 33 university teams were still seriously repairing the security vulnerabilities at the competition site, a terrifying voice sounded.

"Congratulations to Foggy City University of Arts and Sciences for successfully solving [Question D] in 27 minutes and 30 seconds!"

The voice fell.

IMMEDIATELY WITH A "BANG", BEHIND XU BIN, CHEN JUN, AND OUYANG CHEN, THE RED BALLOON MARKING "FIRST-PROBLEM-SOLVED" WAS FINALLY RAISED.

I don't know if it's a special design or a coincidence, but the balloon that rose after the first solution to [Question D] at Fog City University of Arts and Sciences is actually red, doesn't this mean that it is the red of the East?

Perhaps, this is just a coincidence.

"Principal Ding, red balloons, Director Xu, they're also amazing, they're the first to solve this problem!

Seeing this, Wen Ruohan was already excited.

After all, this is the first time that the first place in Fog City University of Arts and Sciences has solved a problem, but Wen Ruohan doesn't know if 27 minutes and 30 seconds is fast.

In fact, Ding Yue doesn't know if this is fast, it depends on how long it will take for the second place to pass [Question D].

Only the judges of the judging group of the competition committee know that the time of 27 minutes and 30 seconds has broken the record in the previous security vulnerability repair topics.

"Fog City University of Arts and Sciences, are they so fast?"

A contestant from Haicheng Jiaotong University, a participating university in the same Xia Guo Division, exclaimed.

"It's fast enough, it's a bit of a BT, but don't waste time, hurry up and fix the security vulnerability. Another contestant from Haicheng Jiaotong University hurriedly said.

There are many universities such as St. Petersburg State University, Imperial College of Education, California Polytechnic University, Moscow State University, etc., who are also dumbfounded after hearing that Wucheng University of Arts and Sciences was the first to complete the repair of the security vulnerability in 27 minutes and 30 seconds.

Some people are dumbfounded, some people are happy.

The happiest is naturally Ding Yue.

"Hahahaha, Abin really didn't disappoint me, and he started to take the first place. Ding Yue nodded contentedly.

At the same time, Ding Yue was also silently calculating in his heart, how long would it take for him to accumulate time results from Fog City University of Arts and Sciences, and he could temporarily rank first?

At present, St. Petersburg State University, Moscow State University, Imperial College of Technology, California Polytechnic University, Haicheng Jiaotong University and University of California, Berkeley are ranked ahead of Foggy City University of Arts and Sciences.

There are six in total.

Among them, the difference between Haicheng Jiaotong University and the University of California, Berkeley and Fog City University of Arts and Sciences is actually less than 30 seconds.

Now, 30 seconds have passed.

And these two universities still haven't solved the problem of this security vulnerability.

This also means that the cumulative time performance of Wucheng University of Arts and Sciences has surpassed that of Haicheng Jiaotong University and the University of California, Berkeley.

The time gap between the previous four universities and Foggy City University of Arts and Sciences is at least 1 minute or more, and even St. Petersburg State University is currently more than 5 minutes away from Foggy City University of Arts and Sciences due to winning the first place.

In the next four and a half minutes, Ding Yue's mood has always been apprehensive.

However.

Four-and-a-half minutes passed quickly.

At this time, Ding Yue was both surprised and puzzled.

What's going on?

Why haven't other universities solved this problem of fixing security vulnerabilities?

At this time, even if St. Petersburg State University passes [Question D], it will not be able to surpass Foggy City University of Arts and Sciences.

The first for the time being, it has been firmly grasped.

[Live Room of Science and Education Channel of National Television Station]——

"Hahahaha, our Fog City University of Arts and Sciences is awesome, and now we can rank first in the time results, right?"

"This is amazing, and the problem of fixing security vulnerabilities was solved so quickly. ”

"First?"

"What? Fog City University of Arts and Sciences won the championship?"

"Uh, uh, don't talk nonsense, it's just that the score should be the first for the time being, and it's hard to say if you win the championship, after all, there are three questions behind, and one question is more difficult than the other. ”

The domestic audience is already boiling.

To everyone's surprise, Foggy City University of Arts and Sciences was temporarily ahead, and it seems that everyone had underestimated the strength of this university before.

In fact, many people think that there is an element of luck when they go to Wucheng University of Arts and Sciences this time, and they just go to soy sauce.

But from the first question to the fourth question now, everyone has seen it, and the performance of Fog City University of Arts and Sciences has always been very good.

It wasn't until the fourth question was solved so quickly that it completely changed everyone's opinion of Fog City University of Arts and Sciences.

Now, among the three universities participating in the ACM competition in China, the strength of Wucheng University of Arts and Sciences and Haicheng Jiaotong University has been recognized by the audience, and everyone believes that these two universities have a chance to win the championship.

As for Northwestern University of Science and Technology, it can only be said that there is indeed a little gap in strength, but Northwestern University of Science and Technology is in the second echelon, and the results are already quite good.

However, Northwestern University of Science and Technology is basically out of the competition for the championship based on its current time results.

Unless Northwestern University of Science and Technology suddenly emerged at the time of the seventh question and solved the problem in super fast time, this is almost impossible.

As we all know, the seventh question is simply difficult to get to the sky.

35 minutes have passed since the solution time of this fourth question, Ding Yue took a deep breath, thinking that it has been 35 minutes, and there are still no other universities that have fixed the security loopholes?

This!

It's so cool!

Because the later the time, it means that the more advantage your Fog City University of Arts and Sciences can get on this question.

Backbite!

Finally, after another minute or so, the "tick" sounded.

Immediately afterwards, the competition committee announced: "Imperial College London successfully passed [Question D] in 36 minutes and 49 seconds!"

Backbite!

"St. Petersburg State University successfully passed [Question D] in 37 minutes 01 seconds!"

Backbite!

"Cal Poly successfully passed [Question D] in 37 minutes and 55 seconds!"

Backbite!

"Haicheng Jiaotong University successfully passed [Question D] in 38 minutes and 44 seconds!"

Since Imperial College London successfully fixed the security vulnerability, the strongest universities in the first echelon have also been successfully completed.

The gap between you is not big, but compared to Fog City University of Arts and Sciences, the gap is huge.

The time for this question is nearly ten minutes short!

St. Petersburg State University was a bit awesome, and the question was less than ten minutes short, plus his advantage of the previous five minutes.

This means that there is actually a difference of about three or four minutes between St. Petersburg State University and Foggy City University of Arts and Sciences.

Ding Yue remembered this St. Petersburg State University as one of his biggest competitors on the road to winning the championship.

Of course, in fact, Imperial College London, Haicheng Jiaotong University and Caltechnic University are strong universities that should not be underestimated.

The fourth question made a big difference in the results on the field at once.

Some colleges and universities that were originally in the first echelon actually fell directly to the second echelon because of this security vulnerability repair problem.

Some colleges and universities in the second echelon have been ranked in the first echelon because it took more than 40 minutes to solve the security loopholes.

But the college teams at the end of the crane are basically the same, and the dishes are still the dishes.

In particular, the University of Cape Town, from Africa, they again and again failed [Question D].

It seems that every question is difficult for the three contestants of the University of Cape Town team, I wonder how their alumni feel when they see the competition?

After the end of the fourth question, it will be clear who has a chance to win the championship and who is just here to play soy sauce.

The fifth question does not seem to be as difficult as imagined.

Moreover, the time for solving the fifth question given by the competition committee is only 20 minutes, which is actually the shortest time to solve the problem.

However!

Just because the fifth question is short doesn't mean it's not difficult.

It's because there aren't many programs required for this question, but it's really difficult, and many second-tier colleges and universities are racking their brains and still don't know how to solve this program problem.

The universities at the top of the first echelon are still very calm.

It seems that even the fifth question can't stop them.

Xu Bin, with the perfect cooperation of Chen Jun and Ouyang Chen, used 11 minutes and 27 seconds to pass the third place in this question.

The time gap between the top two and Fog City University of Arts and Sciences is only one minute at most.

This means that although the fifth question, Fog City University of Arts and Sciences is not the first to solve it, but the current cumulative time score, Fog City University of Arts and Sciences is still temporarily ranked first.

"If this can be stabilized, it looks like we have a chance to win the championship!" Huang Youjie looked at the cumulative time results near the end of the fifth question.

Foggy University of Arts and Sciences ranked first, St. Petersburg State University second, Imperial College London third, California Polytechnic University fourth, Moscow State University fifth, Haicheng Jiaotong University sixth, Nanyang Technological University seventh, University of California, Berkeley eighth, ETH Zurich ninth, Stanford University tenth.

Speaking of which, Stanford University is a super-well-known world-class university in the Eagle Sauce Country, and it is also among the best in the global rankings, sometimes even in the top three.

But!

In the ACM competition, Stanford University's performance is not very good, it may be that the strength of their three-member team is indeed compared with the previous universities, there is still a certain gap.

At the moment, it seems that the favourites are clearly in the top 10.

Ding Yue is looking forward to that, as Lao Huang said, as long as his Fog City University of Arts and Sciences is stable, will the championship be within reach soon?

But the sixth and seventh questions are coming soon, and whether this can be stabilized or not really has to be put into a big question mark.

If you can win the championship, you can be a blockbuster, at least in the computer science field.

If you can't win the championship, even if you shine in the fourth question, it will be useless, because in the end, people only focus on the championship.

"Whew. ”

Ding Yuechang exhaled a long breath of turbidity, and then said to Lao Huang: "I hope Abin can stabilize it, of course, it would be great to be able to create a score like the fourth question." ”

"yes!"

Just as Ding Yue and Huang Youjie were chatting, the competition committee announced that the sixth question had begun.

The difficulty of [Question F] is directly full, and it takes an hour to answer the question, of course, at this time, the time set by the competition committee.

That is, the problem [Question F] must be solved within one hour, otherwise the question will be regarded as a failure, and if you do not pass, you will not get a grade.

And for those college teams that have the opportunity to compete for the championship, if they can't get a score in this question, they will go straight to GG.

The sixth question is more difficult than many colleges and universities expect.

"This ...... It's almost impossible!"

"It's so hard!"

"An hour? I spend a day, and I may not be able to do it!"

"Mike, let's get started!"

"Hurry up, hurry up and give it a try!"

Many students from well-known colleges and universities were a little discouraged after seeing the sixth question.

In fact, even Xu Bin frowned.

Chen Jun and Ouyang Chen, who were on the side, also looked very anxious.

"Director Xu, I'm afraid this question will not work just by me and Ouyang Chen's analysis. Chen Jun said to Director Xu seriously.

"I know, but it's okay, let's try to solve this problem together, and you can provide as many ideas as you can. ”

Although Xu Bin frowned, he did not panic.

Because he knows that he must be calm at this time, once he is in a mess, it is really possible that he will not be able to solve this problem in an hour.

It is said that there are three stinkers, and Zhuge Liang is the top.

What's more, Xu Bin, Chen Jun, and Ouyang Chen are not stinkers, but genius college students majoring in computer science.

When the three of them work together, it might work wonders.

Xu Bin is a computer major, because he has a very hobby and good ability, plus in the more than a year at Wucheng University of Arts and Sciences, there is also the bonus of learning BUFF, as well as various small plug-ins given by Ding Yue.

When Xu Bin faced the problem of ACM competition, he did not say that he was not absolutely sure, but he was not without confidence.

However, unlike Xu Bin, the participating students from several other universities were a little depressed.

They didn't have much pressure to solve the first five questions, and at most the fourth question took more time.

But in this sixth question, some students have even begun to get a little frustrated.

"I don't think we're going to be able to solve this program in an hour!" Wilk of the University of California, Berkeley, Eagle, sighed.

"Hey, Wilk, we're going to get the confidence up!" Wilk's teammates encouraged.

"But ......"

It can be seen that even the participating teams of the University of California, Berkeley, are already on the verge of collapse in answering questions.

This is currently in the top 10 universities!

One can imagine how desperate the participating teams from other universities, and even the second-tier universities, were when they faced the sixth question.

At this time, the mindset is very important.

Xu Bin, Chen Jun, and Ouyang Chen of Wucheng University of Arts and Sciences analyzed this [Question G] in an orderly manner.

Finally, Xu Bin had an idea.

"Look, is it okay to try to solve it like this?" Xu Bin asked Chen Jun and Ouyang Chen as he operated.

The two of them looked at it carefully and were not very sure, but they both nodded and said in unison: "Director Xu, I think you can give it a try!"

"Good!"

Xu Bin took a deep breath, thinking of what his good brother principal Ding Yue expected of him, so he gritted his teeth and began to try to solve [Question G].

Even if this method doesn't work, Xu Bin thinks that there should be a chance to change the solution.

But this method has to be tried.

On the side of the competition committee, at the time of 31 minutes, they received the "answer sheet" submitted by Imperial College London.

However!

The result given by the panel of judges is - WA!

That is, the meaning of the wrong answer!

According to the rules of the ACM competition, if the program submitted within the specified time period is not running correctly, the program will be returned to the team, and the team can make changes and submit the question again.

In other words, all participating universities have the opportunity to consciously try and make mistakes.

It's clear that Imperial College London is gambling that the first time they submit a process will pass.

Once it can be passed, then it is estimated that it can be a large lead.

Because of this problem, everyone feels that if they can solve it, it will take at least 50 minutes to go up.

Backbite!

"Imperial College London submitted an incorrect answer!"

The competition committee returned the procedure of Imperial College London, and the three contestants of Imperial College London were directly stunned.

"It's over. ”

"There are more than twenty minutes left, shall we try Plan B?"

"That's all there is to it, hurry up. ”

After the three of them were frustrated, they quickly adjusted their status, and if plan A was running wrong, then they could only execute plan B.

Like Imperial College London, Moscow State University has chosen both AB options for trial and error.

Almost identically, after the A plan of Moscow State University was submitted, it was rated by the jury as WA!

It was then returned to Moscow State University, and they immediately began to work on Plan B.

However, time is already running out, and there may not be a chance that Plan B will be fully realized.

In fact, Xu Bin of Wucheng University of Arts and Sciences also implements the same method as Imperial College London and Moscow State University.

It's about trying first, and if it's wrong, trying another option.

But when Xu Bin was writing the program, he found that there seemed to be no problem with this idea, and after the assistance of Chen Jun and Ouyang Chen on the side, Xu Bin now just wants to improve the current answering method as soon as possible!

"Brother Yue, several colleges and universities have submitted programs, but they are all wrong, this is trial and error, right? But how did I find out that Ah Bin and they didn't mean to prepare for trial and error?"

Huang Youjie saw the difference, so he asked Ding Yue curiously.

"The best way to do this problem is to do trial and error, if Ah Bin and they are not going to use this method, it can only explain one problem. ”

Ding Yue said, a smile suddenly appeared at the corner of his mouth.

"What's the problem?" asked Lao Huang impatiently.

"That's Ah Bin, they have the confidence to solve [Question G] directly at one time!"

During the 30-minute to 45-minute solution time, colleges and universities continued to submit answer sheets, but the replies from the jury were all - wrong answers!

In other words, the way they try to make mistakes in a short period of time is basically wrong.

As a result, many colleges and universities have almost given up on this question.

With twenty or ten minutes left, it's almost impossible to run the second solution perfectly.

Of course, there are also some awesome university teams that are confident, such as Imperial College London and Haicheng Jiaotong University.

At 53 minutes.

Xu Bin finished typing the last line of code, and then looked at Chen Jun and Ouyang Chen.

The two nodded in unison.

Once submitted, it's okay to pass, but if it doesn't, it's a bit miserable, and you may even lose the chance to compete for the championship.

After all, if the program fails to run, there are still seven minutes left, and it will be too late to change the other way.

Xu Bin saw that the two of them had firm eyes, and his heart was also horizontal!

Submit!

About half a minute passed.

Backbite!

"Congratulations to Foggy City University of Arts and Sciences for successfully solving [Question G] in 53 minutes!"

Bang!

As the purple balloon rose from behind Xu Bin, Chen Jun, and Ouyang Chen, the first university to solve the sixth question was born.

Foggy City University of Arts and Sciences!

The audience even applauded.

Because it has been 53 minutes, the first university has finally successfully solved [Question G].

It can be seen that this question is really difficult.

Of the more than 30 colleges and universities, at least about 10 have given up.

There are also about 10 participating university teams that feel that they are too late.

The rest are some of them missed the first attempt, and some of them are going to the dark like the Fog City University of Arts and Sciences.

Backbite!

"Cal Poly successfully passed [Question G] in 55 minutes and 09 seconds!"

In 55 minutes, Caltech solved this difficult problem.

In the next five minutes, Imperial College London submitted the second answer sheet, which also passed, and Haicheng Jiaotong High University passed it in 58 minutes.

St. Petersburg State University passed in 59 minutes.

Answer sheet submitted by Moscow State University - Wrong!

Now it's okay, Moscow State University is directly cool, and the sixth question did not get a result.

Nanyang Technological University actually stepped on the timeline and passed [Question F].

The sixth question directly kicked other participating universities out of the championship competition.

In other words, champions can basically only be born from Fog City University of Arts and Sciences, Imperial College London, St. Petersburg State University, Haicheng Jiaotong University, California Polytechnic University, and Nanyang Technological University.

Nanyang Technological University, on the other hand, has a relatively poor cumulative time score, so it is not very difficult to compete for the championship.

At this moment, Ding Yue's heart had already risen to his throat.

The last question will determine the winner!

The competition committee announced the seventh question!

The difficulty of the seventh question, after the participating teams from other colleges and universities saw it, they were not interested in solving the problem.

Because of this difficulty, it is even more difficult than the sixth question.

If this program can be completed, there will probably be no problem in working as a chief engineer of computer programs in any computer company in the world, right?

The three contestants from Haicheng Jiaotong University had that expression on their faces after seeing the seventh question.

"Gan! this ...... It took an hour and a half, but how could it be done?"

"Nima, give me a month, I may not be able to solve it. ”

"The topic of this year's ACM competition is too BT, right?"

The three young lads were a little desperate.

After a while, one of them calmed down and said, "Maybe there are other shortcuts to solve this procedure, otherwise how could the competition committee let us spend an hour and a half to solve this procedure that the team can only solve in a month!"

"Makes sense!"

On the side of Wucheng University of Arts and Sciences, Xu Bin, Chen Jun, and Ouyang Chen are analyzing this question.

[Question G] is really super hard.

After Ouyang Chen saw it, he was dumbfounded.

Chen Jun is a little better, and he can barely analyze it.

Xu Bin frowned all the time, because he also felt that this question seemed unlikely to be completed.

But when you think about it, it shouldn't be.

How could the competition committee come up with a problem that was impossible for almost everyone?

"There it is!"

At this moment, the genius's idea is always different from others.

"Director Xu, do you have an idea?" Chen Jun asked, his eyes widened, and he looked at Xu Bin.

At this moment.

On the side of St. Petersburg State University, the three players were calm.

The three contestants from Imperial College London were in a heated discussion.

These players are all known as geniuses, and they don't actually come to participate in the ACM competition, but they can easily go to work in any top computer company in the world by virtue of their grades in school.

Even among them there are masters in the hacker circle.

For example, a player at Imperial College London is a master in the global hacking community, codenamed "Mediterranean".

There was a long silence at the game.

Because the seventh question takes up to an hour and a half to solve.

In the first hour, none of the participating university teams submitted their answers.

One hour and twenty minutes.

Still not!

At one hour and twenty-two minutes, there was finally movement on the field!

Backbite!

"Congratulations ......"

When Ding Yue heard the word congratulations, his pupils suddenly tightened.

Because he knows that the college team that solved the seventh question was born, and the champion was very likely to be born in this way!
