Chapter 54

The host of this game is Director Xia Jianzhong.

He walked onto the stage with a smile.

"Briefly introduce the rules of the game. Director Xia looked at the twenty-six teams in the audience and said with a smile, "This game adopts the mode of score accumulation. ”

"Each question has its own score, and the team that answers first and answers correctly will receive the corresponding score. ”

"The top three teams will receive gifts from the four major universities and our Chinese Mathematical Society. ”

Director Xia opened the briefcase.

Inside, a stack of brand new books emerged.

And these books are nothing else, they are the complete set of textbooks of the university mathematics department: "Advanced Algebra", "Analytic Geometry", "Mathematical Analysis", ......

The crowd was speechless.

But Director Xia didn't look embarrassed, and continued to speak, "At the same time, there is no elimination system this time. For those teams who are unwilling to participate, we have also prepared melon seed snacks, and everyone is happy to be a spectator. ”

Although Director Xia said this, no team chose to be an audience.

Although there is no elimination, there is a ranking!

Ranking, it means fame!

No one wants to be left behind.

Especially those strong provinces in the competition, they are now full of fighting spirit.

The game is ranked on a team-by-team basis.

In this round so far, they have the most people left, and they have a great advantage.

If this can't compare to the teams with only one or two players left, then they will simply have no face to return to the province.

At the front of the classroom, Zhao Kun looked at the nine team members around him, and he had a feeling of high spirits.

He instructed the students, "Get serious for me, this time, our goal in Jiangsu and Zhejiang Province is to protect two and fight for one!"

In another corner, Gu Lu and Bi Qi Ma Zhengxuan were sitting together.

Bi Qi glanced at Gu Lu and pleaded in a tone, "Teacher, can you give me a little bit this time...... Opportunity to perform?"

Gu Lu nodded, "Well, I'll take it in time." ”

............

"Okay, I see that many teams are already gearing up and can't wait, so I won't be too long-winded. Now, let's take a look at the first question!"

On the stage, Director Xia turned on the projector and projected the first question onto the screen.

Shown in the curtain is an 8 x 8 grid.

In the grid of the palace, the sixty-three numbers of 1~63 are completely randomly filled in each small square.

And in the lower right corner of the grid, there is a small square with no numbers filled.

Director Xia opened his mouth to explain, "Digital Huarong Dao, a small game that has been very popular recently, the rule is to move the randomly arranged numbers in the palace grid, according to the order from left to right, from top to bottom, neatly arranged in turn!"

"However, we usually see 4*4 or 5*5 squares, but today we are going to challenge 8*8 squares. Moreover, the purpose of this question is not for you to restore him, but for you to calculate the minimum number of steps you need to move the block to restore the 8*8 version of the number Huarong Dao in front of you!"

Director Xia made the topic very clear.

It is to ask everyone to solve the minimum number of steps required to restore the 8*8 version of the digital Huarong Dao in front of them.

The questions are easy to understand, but the answers are not so easy.

One way and one way to try, this is obviously irrational.

If the number of palace grids is small, you can still use this method, but now it is 8*8, and there are at least tens of thousands of restoration methods, and it is completely infeasible to try them one by one.

Modeling is automatically calculated, which is really reliable.

But the problem is that there is no computer in front of me, only pen and paper.

"Teacher, what are we going to do?" asked Zhao Kun a team member from Jiangsu and Zhejiang provinces.

Zhao Kun closed his eyes and frowned, "Don't bother me, I'm thinking about it." ”

The coaches of the other teams were similar to Zhao Kun, and thought about the idea of solving the problem.

It is worthy of being a question that requires team combat, and the difficulty of the question alone is not at the same level as the previous test questions.

It takes a lot of time to solve.

At this moment, a fluttering voice sounded in the classroom, "Director Xia, I have already calculated it, can I answer?"

Gu Lu looked at Xia Jianzhong with calm eyes.

Poof——!

Xia Jianzhong, who was drinking tea, was choked.

According to him, if you want to solve this problem in ten minutes, you must at least have the level of a doctoral student in the Department of Mathematics.

But how long did Gu Lu take.

Doesn't it seem like a minute?

This Gu Lu ...... Has it become so strong now?

His real level is no weaker than that of a professor in the mathematics department of an ordinary university.

After coughing a few times, Xia Jianzhong eased up, "You, you can just say the answer." ”

Countless people turned their heads and looked at Gu Lu in unison.

Gu Lu said a number unhurriedly, "148!"

Everyone looked at Xia Jianzhong again, waiting for Director Xia's answer.

"The answer is correct!" Director Xia was not as verbose as the host on TV, and gave the answer directly.

Wow~~!

In the classroom, there was a sudden uproar.

But most of the people who speak out are students, and at their age, the worship of the strong is blind.

Many coaches sink in their hearts, grinning on their faces, and MMP in their hearts.

Under the leadership of Xia Jianzhong, he had to applaud Gu Lu's performance just now.

"Qidong team adds five points, next, let's look at the second question!"

As soon as the topic was finished, Gu Lu stood up directly.

"Teacher Gu, who are you?" Xia Jianzhong was surprised.

"I have the answer. Gu Lu was calm.

The rest: "???"

Are you so open!!

Could you please give this question a little respect?

After three seconds of appearance, you were directly knocked out, and you will make the professor who made the question very faceless!

Xia Jianzhong covered his forehead, "Then, then you can say it." ”

“16。 ”

The answer is correct. ”

............

Question 8.

Gu Lu got up.

"Answer?" Xia Jianzhong was weak.

“12.78%”

...... "Xia Jianzhong," "Correct." ”

The audience who saw this scene was numb.

There are even a few teams that have given up on themselves, eating melon seeds while watching a good show as an audience.

In the front row, Zhao Kun looked dejected.

This time, he really realized that in terms of personal strength, the gap between him and Gu Lu was a heavenly existence.

He also boasted before that his individual strength was unbeatable among all the coaches who entered the camp.

But now it seems that it is really a big joke.

Question 9, Gu Lu got up again.

Xia Jianzhong looked at Gu Lu with a tired face, "Teacher Gu, please sit down!"

"Give others a chance to perform!"

"Yes. Gu Lu nodded, sat down, and exchanged glances with Bi Qi.

Bi Qi immediately understood, and his face showed a touch of joy.

Now, it's finally his turn to perform!

But it turns out that Bi Qi is still invincible with two fists and four hands.

Without the pressure exerted by Gu Lu, the rest of the team was like a beast that had been released, showing incomparably bloody.

Bi Qi and Ma Zhengxuan are just two people, and their strength is not as good as that group of experienced coaches.

Bi Qi didn't show it in the end, let alone repeat the myth that Gu Lu had just now.

As a result, naturally because of the advantages laid by Gu Lu in front of him, Qidong Province won the first place.

Bi Qi took the full set of university mathematics textbooks as a prize from Xia Jianzhong with an unhappy face, and looked at Gu Lu who was floating away with envy.

............

ps: The second question of yesterday's bounty has already been made by the big guy, and if you are interested, you can take a look at the answer.
