Originally, Zheng Tongya has always regarded Shen Lei as his biggest competitor, after all, Shen Lei's performance in the first year of high school almost copied his miracles in the first year of high school, and even Shen Lei's data was slightly better than Zheng Tongya. In the face of such a junior opponent, Zheng Tongya naturally did not dare to slack off, especially in this kind of competition, Zheng Tongya always maintained a high-intensity learning state, but he was afraid that his performance would not be as good as Shen Lei.

Under such learning intensity, the performance of Zheng Tongya and Shen Lei can be said to be equal, each has wins and losses, if you leave aside the results in the competition, both of them have the strength to impact the national gold medal.

But since the last final exam, Zhang Xingchen successfully squeezed him out of the first place in the grade, Zheng Tongya has never had to re-examine Zhang Xingchen. Through the observation of the past few days, Zheng Tongya found that Zhang Xingchen's mathematical learning ability was not below him and Shen Lei at all, and he even had a hunch that Zhang Xingchen might be more talented in mathematics than him and Shen Lei!

Zhang Xingchen and Shen Lei belong to the kind of mathematical geniuses who naturally awaken, and they can fully display their talents in mathematics as soon as they go to school. Zhang Xingchen belongs to the kind of genius who needs to be awakened, this kind of student will show his learning advantages in a certain subject when he goes to school, but he can't fully use his natural advantages, and he needs someone to guide him in learning methods in order to give full play to his greatest natural advantages.

For Zhang Xingchen, Tao Li is the one who guides him to his greatest potential!

"I only have a preliminary idea, but after writing this, I don't know how to proceed with it. Why don't you help me take a look, and maybe I can come up with a complete solution to this question. Zhang Xingchen scratched his head, and then generously handed over his scratch paper.

He has always been like this, low-key and warm-hearted, which is why Tao Li values him so much.

Zheng Tongya nodded at Zhang Xingchen gratefully, and then took the scratch paper he handed over with both hands, and after taking it, he and Shen Lei looked at it seriously.

I didn't think of answering in this way. Just a little glance at Zhang Xingchen's answering process, Zheng Tongya and Shen Lei immediately realized.

The two of them are not mediocre talents, and they are not clueless about this question on the blackboard, they have found the right direction, but they just can't figure out how to go, and the difference is this last kick, and now with the preliminary method given by Zhang Xingchen, the two of them quickly discovered their initial thinking misunderstandings and found the right direction.

"Do you know what to do next? By the time I got to the scratch paper, my train of thought was stuck. Looking at the expressions of the two of them, it seemed that there was already a way to crack it, Zhang Xingchen hurriedly lay on the table and asked in a low voice.

"You sit down a little bit, you see, Xingchen's original idea is right, then according to his initial deduction, we can draw such a conclusion, that is, when n people have taken soybeans, if ......"

When Zhang Xingchen quietly sat next to Zheng Tongya, Zheng Tongya directly picked up the pen, and then Zhang Xingchen's last step continued to be done.

"Oh, I see, if this conclusion deduced by Yago is correct, then according to this plan, you can ensure that you will not be executed, and at the same time, you will ensure that the remaining prisoners who did not take the soybeans will be executed with the highest probability of being executed. ”

Looking at the steps to solve the problem written by Zheng Tongya, Shen Lei also suddenly realized.

"That being said, the conclusion of 96-Mn*n is to ensure that the remaining prisoners have at least one soybean to pick from, and that they have taken at least two soybeans themselves...... In this way, you can ensure that the number of soybeans you take is not the largest, and everyone else can't get so much, so that you will definitely be able to survive and avoid being executed!"

Following their train of thought, Zhang Xingchen also quickly came to such a conclusion. With the help of Zheng Tongya and Shen Lei, Zhang Xingchen cleared the blind spots in his thinking, and the next thing is to let him do it.

…………

In this way, the three students with the best mathematical talent in the classroom sat together, and you discussed this question in a whisper, as the saying goes, three stinkers beat Zhuge Liang, not to mention the cooperation of three Zhuge Liang-level "stinkers", and the final answer to this question will soon be solved.

It's been 12 minutes, do any of you have an answer? ”

Just when most people were at a loss, Tao Li, who was sitting in the front, put down the book and reminded lazily.

Many students just glanced up at Tao Li, and then hurriedly lowered their heads and continued to write, and some students even gave up this question directly, let alone more than ten minutes, even if they were given another hour, they would not be able to do this question.

Many times this is the case, there are some questions you don't know or can't, and it doesn't have much to do with how long you are given time to solve the problem, because that question is likely to be your knowledge blind spot, and it doesn't take much time to make it up.

"Okay, I'll give you another five minutes, and I hope that some of my classmates will give me a satisfactory result. Tao Li picked up the book again and said very leisurely.

Five minutes is nothing to Tao Li, he just wants the students to understand that math is not as simple as they think!

"There are still five minutes left, can you get the final result?" Shen Lei looked at the time and asked with a somewhat hurried expression.

Although the three of them have worked together to write most of the content, the final conclusion is still not reached.

From the conclusions we have made, we can conclude that whatever the strategy of choosing soybeans is, the first prisoner must be put to death, and then it depends on what the strategy of the first prisoner is. Zheng Tongya said while furrowing his eyebrows.

"The situation is that if the first person chooses to let everyone die, then he can take 96 soybeans, and then everyone will be put to death. But if the first prisoner chooses another strategy, which is to keep more people alive, then what is the range of soybeans he should take?" Zhang Xingchen also said quickly while writing on the paper.

We're pretty close to the final result!

Time passed minute by minute, and the vast majority of people had completely given up struggling, they were really powerless to do anything about such a question, only Zheng Tongya and the three of them were still struggling to make the final attempt.

"Okay, when the time comes, is there any student who would like to talk about the results?" Tao Li put down the book and stood up at once and asked.

The entire lecture hall was deadly silent.

"No one knows what the answer is? ”

Tao Li glanced at it, and then said lightly.
