Chapter 83 Identity Exposed
"Wow, I knew it."

"Teacher Zheng is cheating again..."

"It sounds like a simple math problem...but why do I feel like my brain is not enough? Am I really a high school student? I'm useless."

"I can't even answer such a simple question for junior high school students... What's the point of my life?"

"Does anyone know the answer? Yang Ning."

Yang Ning stood up.

"Teacher... I... this question... I... I haven't figured it out yet."

Zheng Yihang smiled slightly and said, "Don't be nervous, don't be nervous, this is a little puzzle game for normal teachers and students to get closer. It doesn't matter if you don't know it, just sit down."

"Zhang Yang, what about you?"

Zhang Yang stood up, "Teacher, give me some time, I already have an idea, I believe I can come up with it soon."

"It's okay, you should sit down first."

"Lin Hai, what about you?"

Zheng Yihang called the next student, who was the best performer in the previous two questions, and wanted to see their logical thinking ability.

Lin Hai stood up and said, "Teacher...are there three?"

Zheng Yihang's eyes lit up slightly, and he continued, "Go on, how did you get three?"

"I just figured it out, but there are no steps to solve the problem yet."

"I see, you sit down first."

Zheng Yihang also asked Lin Hai to sit down. Lin Hai is a good classmate, but he still lacks some talent in some aspects.

Then, Zheng Yihang called Fu Shaohua and Guo Xiling successively to answer.

It's a pity that neither of them had the right idea. This question looks very simple, but if you really look at it, this puzzle question is also not easy.

Afterwards, Zheng Yihang's eyes fell on Fang Chao, "Fang Chao."

"Mr. Zheng."

"What do you say? Do you have an answer?"

"Three."

Fang Chao answered the same answer as Lin Hai.

Lin Hai looked at Fang Chao, I said this answer just now, why are you saying it now?

Zheng Yihang said, "Come, tell me what you think."

Fang Chao didn't go to see Lin Hai. Although Lin Hai had the correct answer, but he didn't have the correct thinking to solve the problem, he could only get a consolation point, and it was impossible to get a full score.

"Suppose the people wearing black hats are A, B, and C. Thinking from A's perspective, A sees B and C wearing black hats. A thinks: B saw C wearing black hats when the lights were turned off for the first time. It satisfies "at least one black hat", so B cannot be sure whether he has a black hat and cannot clap, and if only C wears a black hat, C will clap when the lights are turned off for the first time. But C will not clap when the lights are turned off for the first time. Clapping, this means that C is also waiting for others to clap, and B will know that he is also wearing a black hat. When the lights are turned off for the second time, both B and C will clap. But they did not clap when the lights were turned off for the second time, which means that B and C They also saw two black hats each, and A deduced from this that he was wearing a black hat. The same is true for B and C's logical reasoning. The other people wearing white hats also reasoned like this, and they will wait for A and C when they turn off the lights for the third time. B and C clapped, so when the lights were turned off for the third time, only three people clapped, so this is the answer.”

"Boss is so awesome!"

"Although I don't understand it, it feels right!"

"It's amazing. Is this the world of the strong? Who is he? He is so powerful... There is such a big guy in our class."

"Looking at it this way, he actually looks pretty good. I'm a little bit excited. My mother and the others won't object to the two being together, right?"

Zheng Yihang smiled and said, "What you said is just assuming three people, so what if there are five people wearing black hats?"

"Mr. Zheng, if there are five people wearing black hats, this question will be wrong. From the beginning, someone slapped us for the third time and told us the answer, so the sound of slaps can only be heard when the lights are turned off. It means how many people are wearing black hats, but there are only 52 people in our class. If you really want to turn off the lights slowly, I think it is quite boring... Actually, I think it should be like this. If there is only one Black hat, the first time people wearing black hats immediately applaud when they see everyone wearing white. So the result of the first time is that people know that there are at least two black hats and see at least one Black hats. The second time, there was still no applause. If there were only two black hats, then these two people must have applauded when the lights were turned on this time, indicating that there were at least three black hats, and so on..."

"Wow, what a profound boss!"

"Which school graduate is this great master? Isn't this a bit too powerful? I was stunned for a while, but I feel that what he said is right..."

"Is mathematics so interesting? He seems to be called Fang Chao, right?"

"Why do I feel like I've heard this name somewhere?"

"Popular names, what's so strange, just like Wei, Chen Wei, Lin Wei, Wang Wei, etc., there are a lot of them, Chao is not without it, Chen Chao, Yang Chao , Lin Chao is not all, a Fang Chao, I am sure you have heard of it somewhere."

"No, a very famous person, I must have heard of it..."

At this time, Yang Ning, Pan Mingming, Lin Hai and the others seemed to have thought of something, and looked at Fang Chao in disbelief. They had some guesses about Fang Chao's identity, but they didn't dare to confirm it.

At this time, Zheng Yihang looked at Fang Chao and said, "I have always known that there is a winner of the CMO provincial and district perfect score championship in our class. When I see him today, it is really extraordinary."

"What? The winner of the CMO preliminary competition?"

"Damn it, this thing is very valuable..."

"I thought I was strong enough, but I didn't expect that among the strong, there would be a strong one. No one has achieved perfect scores in the past few decades. Just this year, there was a CMO provincial and district perfect score champion, but I didn't. I don’t know his name, but I only know that he must have entered the No. [-] Middle School of the city. I originally thought he would be assigned to Class [-] or Class [-], but he didn’t expect to be assigned to Class [-], which is quite stressful now.”

"In vain, I used to be number one in mathematics in the class, but I can't pretend to be tough in this class anymore. The days when I can't pretend to be tough are very boring..."

"Why, why, since Shengyu, He Shengliang!"

"..."

At this time, many people looked at Fang Chao completely differently.

Fang Chao looked shy, "Don't look at me like this, everyone. I'm just the champion of the preliminary round... I don't want to either. My goal is to win this year's IMO International Individual Gold Medal."

"Damn it, you're the king!"

"This is the real bully king. Compared with him, what are the bullies I pretended to be?"
