The day when the Hope Cup final began, it was the day after Hao Yun and his party arrived in Shanghai.

Gymnasium of Xiadong Normal University.

The movable door panel divides the huge field into 270 small and small open-top compartments. Each compartment houses a computer, and all computers are connected to a central server that is managed by a unified examination room system.

The competition time limit is three days, and participants must eat, sleep and sleep in the cubicles for three days, and can apply to go to the gymnasium's toilets at any time, but they will have to go through an additional security check in the stadium to enter and exit.

However, according to the practice of previous editions, many people completed their works in one day, and there are not many people who spend three days here.

After all, even if there is a bathroom to use, it is difficult for people who love cleanliness to not take a shower and not change their clothes for three days.

According to the rules of the competition, participants can bring decorations such as posters and figurines into the examination room, and they are free to decorate their booths one hour before the start of the competition.

After all, for a "designer", the environment also has a great influence on inspiration.

Especially for an open programming competition such as the Hope Cup, professional knowledge and skills are only the threshold for participating in the competition, and if you want to stand out from many design works, it is more of a test of the creativity and brains of the contestants!

As advertised by the tournament organizers, there are no preset answers, and you can even hack the test server to win the contest.

It's just that this is probably the most difficult road.

After all, many experts in the main test committee are information security experts from the Xia Academy of Sciences, and they were playing tricks with masters all over the world when the People's Federation was not unified.

Can you beat them?

Brother, even if you don't win the championship, you have a bright future!

At the entrance of the test site, security personnel are using professional equipment to check the luggage carried by the test takers and eliminate those items that may be involved in violations.

Unlike those candidates who entered the examination room with large bags and small bags, Hao Yun brought nothing empty-handed. Because he heard that computers were provided in the examination room, he simply brought someone over.

Seeing that he was so different, the little brother of the security guard in charge of the security check couldn't help but say more.

"Classmate, don't you bring anything?"

"No, no, I prefer simplicity here." Hao Yun was telling the truth, the table of the four people in their bedroom was the cleanest, and there was nothing on it.

"At least bring a bottle of water, right?"

"I have to go to the toilet to drink water, it's too troublesome." Hao Yun shook his head and declined.

“……”

The little brother of the security guard was speechless, and finally let him go without saying anything.

Hao Yun glanced at the sign in his hand.

Number 101?

How is it not 188?

Forget it, it's all the same anyway.

At the same time that Hao Yun entered the examination room, on the other side of the entire gymnasium, the main examination committee and a group of staff were standing there, looking at the bustling candidates not far away, and sending blessings to them with their eyes.

"I'm really looking forward to it!"

Looking at the busy examination room, the old man standing at the edge of the gymnasium had a smile on his face, touched his chin full of stubble and continued, "I don't know what kind of interesting works will appear in this year's Hope Cup!" ”

"Yes," the middle-aged man standing next to him, with an expectant expression in his eyes, said with a slight smile, "I didn't sleep almost all night yesterday, half of the reason was because of today's game!" ”

The old man's name is Zhan Yongshu, a member of the School of Information Engineering of the Xia Academy of Sciences, who used to do information security technology, but after the new calendar, he began to turn to the research of civil information technology, and cooperated with many well-known Internet companies in Xia Guo.

The middle-aged man standing next to him is his student, named Zhang Cunhao, who graduated from Shuimu University 20 years ago, and later entered Longwei Group as a R&D department, and has been working for 20 years, which can be said to have witnessed the rise of Xiaguo's electronics industry and civil Internet industry.

It was in the past two years that he gradually retired from the front-line R&D position, began to focus on education, and became a professor in the School of Software Engineering of Mizuki University.

"Speaking of which, what is the contestant who was commented as the most creative shortlisted work by Times Youth Daily?" Suddenly remembering something that he was a little concerned about, Zhan Yongshu opened his mouth and asked his students.

After hearing the old man's inquiry, Zhang Cunhao hesitated and replied seriously.

"I'm not mistaken, it should be number 101."

He was also very concerned about this student, after all, he also participated in the panel discussion of the main examination committee whether to let the "Cemetery" be shortlisted for the finals at that time.

By the way, he voted against it, and it was one of the few to vote against.

"Can I see his screen here?" Looking at the candidates who had basically finished entering, Zhan Yongshu continued to ask with interest.

"Yes, yes...... Are you interested in him? ”

"I'm interested." Zhan Yongshu nodded in acknowledgement.

"Then you may be disappointed, this year's four questions seem to test a little more professional knowledge, and this happens to be the type he is good at." Professor Zhang Cunhao said with a smile.

He had read the program written by Hao Yun before, and it couldn't be called a program at all, it could only be said to be a 3D game with no technical content completed with the help of the existing editor.

The reason why such a work can be shortlisted, in the final analysis, there is still an element of tricks, at least Professor Zhang Cunhao thinks so.

And this is the main reason why he voted against it at that time!

"That's why I'm interested," Zhan Yongshu smiled faintly and continued, "My point of view has always been that programs are dead, but people are alive. Technology has bottlenecks, but creativity knows no boundaries. Sometimes creativity doesn't necessarily make up for technical shortcomings, and it can have an unexpected effect at a critical time. ”

Professor Zhang Cunhao: "But it is undeniable that technology is the premise of everything, and it is also the threshold for solving problems. ”

"Yes," Academician Zhan Yongshu nodded, looking at the arena not far away, "so I'm curious, as the only contestant in the preliminaries who made it to the finals with his game works." ”

"In the face of such a professional exam question, what kind of answer sheet will he hand in!"

……

What kind of answer sheet will be handed in?

If he heard the conversation between Academician Zhan Yongshu and Professor Zhang Cunhao, Hao Yun was afraid that he would persuade this old man with a wry smile on the spot, or not to expect so much from himself.

To be honest, when the competition officially started, Hao Yun was stupid when he saw the four exam questions appear in front of his eyes.

Although according to the rules of the competition, he only needs to choose one of these four questions that he will complete. But after looking around, none of these four questions can be written by him?

Question 1!

Please design a set of running supporting software for the industrial assembly line in the attachment, and the required functions include: classification and processing according to the quality level of the parts, return and reprocess defective products, etc. (Please refer to the attachment for details)

It's a very summer-style title.

Looking at the complete collection of past competitions, it is not surprising that such a question appears in the position of the first question, after all, the first question of the previous Hope Cup is from Capital University of Technology, so Hao Yun gave up very decisively after reading the question!

Question 2!

As the Srtam virus swept across the African continent, WHO sent a team of experts to devise an effective plan to stop the spread of the virus. (Note: Solve this problem from a programming perspective)

This topic seems interesting?

I don't know why Hao Yun subconsciously thought of something called a health code, but unfortunately he couldn't remember more details at all, but he vaguely remembered which year before the crossing seemed to have used this thing.

Gan!

"Why is it so hard to have one or two?!"

When he saw the third question again, Hao Yun was about to cry.

It's been ten minutes since the game started!

Although the competition time is very generous, and the organizers even prepare sleeping bags for the contestants to rest and provide online ordering services, it still can't stop Hao Yun from being anxious there.

Isn't it just that I haven't written a single line of code until now?

Wouldn't it, wouldn't it?

Question 3!

In order to adapt to the huge temperature difference between day and night on the surface of Mars, please design an effective temperature control system for the automated farm unit deployed on the surface of Mars according to the Martian surface climate sampling data provided by the Xia National Space Agency. [See attachment for details]

Boy!

The first two questions are still on Earth.

This question simply flew outside the earth?!

However, his intuition told Hao Yun that although this question is difficult to read, it may actually be easier to do than the first two questions.

It's just a pity that even this problem is not at all with his programming ability, and he has been thinking about it for a while and is helpless, feeling that just reading the astronomical data in the annex is like reading a book from the sky.

The requirements of the fourth question are quite simple, optimizing the code of the "Glacier Engine", which requires the engine to run efficiently by at least 10%.

Glacier Engine is the mainstream development engine of today's 3D games, and it is also one of the most mature game engines commercialized at present, developed and operated by Longwei Group ten years ago.

On the surface, this question seems to be the easiest, and at least the 270 contestants sitting here may not have been exposed to assembly lines, epidemic prevention and control, and aerospace, but they must have played or watched others play games.

Of course, Hao Yun thought the same way.

After reading this question, his eyes suddenly lit up, and he felt as if he had grasped a life-saving straw, downloaded the content of the attachment, and began to ponder it repeatedly.

However......

The examining committee sitting here knew very well that this was probably the most impossible of the four questions.

Yes.

The other questions are just difficult.

But this question is almost impossible to complete, and it can even be seen as a time-wasting trap!

A commercially available game design engine that has been tested in the market and has been continuously updated for a decade, and a lot of the code has almost pushed the performance of the computer to the limit.

To put it bluntly, people use an algorithm built up by an unknown number of hairs and sacrifices to an unknown number of code farmers, so why can a college student improve the efficiency of someone's engine by 10% in one day?

Well?

Just ask you why?
