My Identity As A Schoolmaster Has Been Exposed

Ten minutes, say long is not long, say short is not short, fleeting!

Soon, all the students suddenly raised their heads and stared at He Junfei.

Not to mention that the students in the other two provinces were surprised, even the students in this province were surprised.

Because He Junfei was just average among them, not top-notch, but today suddenly broke out, which made them very curious.

"Didn't He Junfei not even have a semi-final? What happened to you today? Isn't it so fierce?"

The truth is, what kind of questions can be done, what kind of questions can be done, what kind of questions will be asked!

Otherwise, it will be even more embarrassing to talk about topics that you don't know how to do it yourself.

In the eyes of the teachers in the other two provinces, He Junfei is very likely to be like this!

"He is bluffing!"

"Feng Hechuan, you continue to prove yourself!"

Before he finished his words, Feng Hechuan got up, holding his own performance paper in his hand, and ran to He Junfei.

He just glanced at He Junfei, without saying a word, just picked up the chalk and wrote on the blackboard:

Proof: Subtracting the two formulas corresponding to n and n+1 can be obtained. For all n ∈ N,

(an/(a(n+1))+(a(an+1)/a1)-(an/a1)∈z(1)

Then there is a(n+1)a1lana1+(a(n+1)-an)a(n+1), n≥(2).

Suppose the prime factor set of a1 is P, and an/an is the largest factor of an that is relatively prime to a1, that is...

Feng Hechuan's thoughts are very clear. The answer to this question is step by step and methodically. He Junfei watched from the sidelines, and he was a little shocked.

People who have this strength are worthy of respect!

But it was only a bit shocking. After all, for this question, He Junfei firmly believes that no one except Xu Cong can give the correct proof process in such a short period of time!

"It deserves to be the third place in this Olympiad! It's too strong!"

"It can be said that Feng Hechuan can crush everyone present! Although I am a little unwilling to say that, my strength proves everything! He is too strong!"

"Look! That student He's face has changed!"

Everyone was discussing below, and some of them couldn't help but clapped, and the applause broke out.

Exciting!

Proud!

After all, Feng Hechuan belongs to their province, and they are now doing questions on stage. This is their pride!

"Okay! Feng Hechuan, great!"

"Look! You say ten minutes, we will ten minutes"

The praise and elation on this side were not over yet, Feng Hechuan, who was proving on the blackboard, suddenly stopped.

Because he has begun to realize that there seems to be something wrong with the problem-solving ideas he has thought of within ten minutes.

He stood on the spot, staring at his narrative with furrowed brows, and sorted out his thoughts from the beginning, trying to see which step went wrong.

He Junfei stood aside calmly, waiting for him to think without arrogance or rashness.

It is impossible for any student present to make this question in ten minutes!

If you can really solve this problem in such a short time, then Xu Cong would be too hip.

After all, this question was given to He Junfei to improve the status of their province's education in the eyes of leaders.

It is precisely because Xu Cong gave this question that He Junfei has no hope for Feng Hechuan!

Even if he can think of proof ideas, it does not mean that he can prove it.

This is totally two different things!

I know how to do it, but my answer is wrong, it is totally different!

He Junfei looked at him still thinking and meditating, and said with a smile: "This classmate, are you okay? If it doesn't work, let me do it! I have the right way to prove it."

Although his voice is not loud, it has a strong smell of gunpowder!

This time, the exchange meeting was not so calm and you could easily pass by.

Feng Hechuan was the third individual in this Olympiad. He was the most impressive among all the participants, not one of them!

If he couldn't even answer it, it would be even more impossible for others. Hearing He Junfei's somewhat sarcastic remarks, he immediately turned his head to look at He Junfei, his eyes full of unwillingness.

His eyes seemed to say to He Junfei: "If you don't prepare in advance, you are nothing!"

"You wait, wait for me to write the question! See if I can embarrass you!"

In the end, Feng Hechuan couldn't figure out where his thinking was wrong, so he turned his head back angrily.

"Wow..."

Everyone saw him directly defeated, and the scene suddenly became an uproar.

"Fuck! Even Feng Hechuan was defeated?"

"Ten minutes is too short!"

"Not satisfied! We are not satisfied! How can you finish this question in ten minutes! Let's talk about it! If you didn't prepare it in advance, would you know the answer?"

The classmates from that province flushed, and one after another shouted against He Junfei.

He Junfei smiled slightly at this and said to them very calmly: "In order to share and exchange more topics with you, I have to hurry up!"

"Otherwise, it doesn't make any sense to stay here for a day and a night!"

With that said, He Junfei erased a small part of Feng Hechuan's thoughts and added it later, and at the same time began to analyze this question.

"His thinking is not wrong, it is right!"

"But! From here, the direction is wrong!"

"Here, we must be clear that the power of the prime factor p must have one of the following situations..."

He Junfei said 6, the chalk did not stop, he kept writing, writing:

In the first type, the p powers of the three fractions are all non-negative integers;

In the second type, the p powers of the three fractions have negative numbers, and the two smallest negative numbers must be the same;

After He Junfei finished writing, he continued to give specific explanations for each situation: "For the first situation, we can get..."

"For the second case..."

Of course, He Junfei is not such a fierce person, but he also holds an essay in his hand, just copy it!

Above is the answer given by Xu Cong...

"Four situations may occur alternately, for n≥N, if..."

...

"Combining with the convergence of an demonstrated above, we can see that an is convergent, that is, there is a sufficiently large M≥N, so that for any m≥M, a(m+1)=am."

At the end of He Junfei's speech, his voice slowly fell.

At this time, there was no sound in the conference room, and the needle drop was audible. Everyone was attracted by the answers he said and written.

At the same time, He Junfei was able to answer the questions with ease, stunned everyone, and the teachers and students of the other two provinces were confused.

They looked at He Junfei and then sideways, and they were also dumbfounded.

Depend on!!!

Did you do it on purpose?

The classmates in your own province have proved it, you are surprised!

Because the classmates who came with He Junfei also looked at the blackboard dumbfounded at the moment, they were also dumbfounded.

Could it be that He Junfei is a hidden boss?
