After having an accurate idea, Fang Chao quickly wiped the earlier draft with an eraser.

Although there are still a few faint traces, it is not painful.

On the blank test paper, Fang Chaoyun's pen was like flying, and the pen was like a god, and there was no longer the slow progress before, the whole speed was amazingly fast, and his thinking continued, this was the simplest of the three questions, but the result was ridiculous that it trapped him for a longer time.

He wanted to understand the advanced knowledge and knowledge, but he neglected the basics.

Accumulate a lot, can he still use it?

He thought it was funny, some complex things he could comprehend at once, but simple things...... I have to say that when he figured it out, Fang Chao's whole spirit was uplifted, and at this time, he was basically sure that he would be able to get a perfect score of 42 points.

Of course, as for whether you can get a full score, it depends on how the main committee gives points, but as a player, if you are not even confident in the test questions you do, how can the main committee give you a high score

Dozens of minutes later, Fang Chao had already written more than twenty steps.

Again, at the last moment, he turned all the n steps into t.

So the final answer came out.

an=bn=1/4n（n+1）

Yes, the question is so simple, not even the answer is complicated.

This question wasted Fang Chao's time of about forty minutes at the beginning, and after he figured out what the problem was, it took a total of about twenty-seven minutes to get it done.

The total time is 3 hours and 33 minutes.

3333

Well, it's not 666, but it's great, isn't it?

This kind of data is perfect!

"Bashi!"

Fang Chao took the test paper, today is the last day, so he can't be careless, so he did a simple review, and after making sure that there was no problem, he put down the pen in his hand, and then handed in the paper and walked out of the examination room of the imo event.

The sky outside was exceptionally bright, several white doves flew through the air, and even Fang Chao's mood became beautiful.

Shen Lang was squatting outside the arena of Fang Chao's exam again, seeing that he was not the first to come out, he was a little nervous, with his understanding of Fang Chao, he was either the first to hand in the papers, it was impossible to wait for such a long time, more than three hours had passed......

Especially as time passes minute by minute, for Shen Lang, the days are absolutely like years.

He was looking forward to the players being able to walk out of the arena at the last moment, but Fang Chao was really an exception!

If he can submit the paper early, he will definitely not delay the submission of the paper, and if he wants to do it, he will be the fastest player......

Waiting, waiting, waiting a little disappointed, a familiar figure appeared in Shen Lang's field of vision.

"Chao'er!"

Shen Lang didn't know when he came to Fang Chao's side, and slapped him heavily on the shoulder, pulling his good mood back to reality.

It's so angry

I just saw two white doves who seemed to be in love, but you scared me, and I'm not in a beautiful mood right now.

"Brother Lang."

"How do you look at your listless appearance, should you not be unsatisfactory on the last day of the exam, you are the ace player of our national team, if even you can't get a full score, then other people want to get a full score is only afraid that it will be more difficult, I don't know which countries are the ones who will ask this year......"

After a pause, Shen Lang sighed, "Okay, if you don't do well in the exam, you don't do well, don't take it to heart, after all, the national team has done its best, but our national team has lost for several years in a row, and this year finally came out with a player like you, but the result is still unable to get a full score, it seems that our national team will still miss the championship team this year......

Fang Chao looked at Shen Lang's sentimental appearance and blinked and said, "I'm just sighing, Shen Lang, do you have any misunderstanding about me?"

Shen Lang was stunned for a moment, he heard the meaning of Fang Chao's words, and immediately said excitedly, "Are you saying that you can get a full score in this competition?"

Fang Chao opened his mouth and said, "Two days, six questions, I spent more than six hours in total, I can guarantee that I will not be wrong with six questions, getting 40 points is certain, but whether I can get a full score depends on the main examination committee, I can't give myself a score, but if I am a judge, I will give 42 points, not one less point." ”

Fang Chao's face was filled with a confident smile, he had absolute confidence in the six questions he had done, but the number of points really didn't depend on him, it had to look at the side of the main committee, but basically 40 points would definitely not be able to run away.

When Shen Lang heard this, he immediately laughed and said, "Okay, Chao'er, if you say forty points, then you will definitely be able to get a full score of forty-two points, with the existence of a player with a full score like you, at least you can pull a lot of points for our total score, maybe this time you can really get the first place in the group, win glory for the country, and wash away the shame of the past few years!" ”

There are only a handful of perfect scorers in IMO events every year, which shows the difficulty of the question, so any perfect score player plays a crucial role in the ranking of the competition, and any score value may affect a ranking.

The Chinese team has been screened layer by layer, and the strongest six players selected from tens of thousands of players are bound to return with high scores!

"My words are so-so and count him 42 points first, so my words, the individual gold medal has already arrived, but for me, this is just the beginning, how it is, it depends on how the five of them play, as long as they play normally, then we have a great chance of winning the team championship!"

"I hope so."

Shen Lang said, and then, he glanced at the time and found that there was still an hour before the game, so he asked, "Chao'er, since you are so confident in this competition, why are you still melancholy about your young age just now, what are you worried about, did you encounter any problems in the examination room With your temperament, it should be the first to hand in the paper, and before you, there were three contestants." ”

"Alas, what should they do if they hand in the paper early, it's just that I play the rest of the things, if I can hand in the paper early, of course I will hand in the paper early, but I have already played this thing yesterday, there is no need to show it again, steady and steady should be what I want to do, I am sad that the young people nowadays are too impetuous, if you want to hand in the paper earlier than me, you should first break my record yesterday, but they are still half a beat slower, in this regard, they still lost to me."

"In addition, I am still wondering if I am invincible among the younger generation, and until now, I have not met an opponent who can compete with each other, and my life is too lonely like snow...... When the results are announced tomorrow, I will get a perfect score in any competition I have participated in, whether my life has been completed, and what kind of things can I still move forward in my high school career that will give me the motivation to move forward. ”

"Brother Shen Lang...... I felt the loneliness of the master...... You know me."

Shen Lang: "......"
