At 7:40 the next morning, Xiao Jun and Yang Qianqian began to enter the examination room.

Since there are a total of 58 high schools participating in the math competition, it is divided into six examination rooms. There are 10 groups of contestants in each examination room, and the last examination room is 8 groups. A school represents a group of contestants, with 2 players per group!

"Hey, there are Jiangbei High School and Jiangbei University High School in the same examination room as us, as well as Wucheng No. 1 Middle School in the same city as us!" After Xiao Jun entered the examination room, he glanced around and saw the players from these three key high schools. Because they are all wearing their own school uniforms, they are very easy to identify! These high schools are among the top five high schools in the province. It's famous all over the country!

The players in the other groups also saw this situation.

"It's so stressful to be in the same exam room with them. ”

"What's the pressure, anyway, we're just a round of tours~"

"Anyway, you guys have a good mentality. ”

“……”

At 7:55 a.m., the invigilator in the examination room began to distribute the test papers.

At eight o'clock, the exam bell rings, and the exam officially begins!

After the test papers were sent, Yang Qianqian began to read the questions seriously, and the time for the exam must be a race against time.

Since it was a team game, two people could discuss.

Because this is not an Olympiad math competition, it is just a math competition held in Jiangbei Province. So the way the exam is done is different. Although the questions on the exam use the Olympiad type of questions.

But Yang Qianqian didn't seem to plan to communicate with Xiao Jun at all, but thought alone.

Xiao Jun looked at the title of the first question: f(n) is a function defined on a positive integer and the value is a non-negative integer, f(4) = 0, f(6) is greater than 0, f(6666) = 1111, and for all m,n there is f(m+n)- f(m)- f(n)= 0 or 1, try to find f.

After reading this first question, Xiao Jun's first feeling was that this question was several times more difficult than the final question of the high exam! Now it's the first question, and that's how difficult it is. When it comes to the second and third questions, isn't the difficulty of the third question going against the sky?

Don't forget, this is the first exam, and won't the title of tomorrow's final be even more perverted?

"Brain-burning!" Xiao Jun had no clue after reading this question. All the high school math books he had read before, the content of his high school math teacher's lectures, or the high school test questions were completely useless.

Then he recalled the content of the teacher's training on Olympiad topics in the past five days, as well as the Olympiad practice problems he had done.

"I rubbed it, I didn't find similar knowledge content! I've never seen this kind of question!" Xiao Jun scratched his hair, feeling helpless. He wanted to help, too, but he didn't have any stock in his head.

Not only Xiao Jun, but many other ordinary high school players are now black-eyed, either shaking their heads or biting the tip of their pens and meditating.

"Isn't it, the first question is so difficult? I wouldn't have come to this competition if I knew it. ”

"No way, the school called me here, and I was embarrassed to refuse. ”

Many candidates are now complaining in their hearts.

Soon, fifteen minutes passed.

Yang Qianqian hadn't started writing yet, but turned her head to Xiao Jun and asked, "How is it, do you have a clue?"

"Also...... No~" Xiao Jun shook his head.

"Then let's take a look at the second and third questions. Yang Qianqian saw Xiao Jun shaking her head, and sighed in her heart. This time, the competition really depends on herself. The other party is purely playing soy sauce!

"Uh~" Xiao Jun didn't know why.

But in the next second, he saw Yang Qianqian start to brush and answer questions on the test paper.

"Rub, it turns out that she came up with the first question, no wonder she asked me to read the second question......"

Twenty minutes later, Yang Qianqian answered the first question!

"Xiao Jun, do you have a clue about the second question?" Yang Qianqian asked Xiao Jun with a sigh of relief after finishing the first question.

Xiao Jun still shook his head.

"......" Yang Qianqian.

"Forget it, don't bother to ask him. Yang Qianqian shook her head helplessly.

She began to think about the second question.

Anyway, so far, Qin Hailang has been playing soy sauce throughout the whole process!

Before I knew it, an hour and a half had passed.

At this moment, Yang Qianqian is writing the second question. I have to say that Yang Qianqian does have two hits. Judging by the way she answers the second question, there should be no problem. If you can get the third question right, then there seems to be no problem in this preliminary test.

"Huh~" Soon, Xiao Jun, who was bored in every way, saw that there was already a participating group that seemed to have finished writing.

"Isn't that Jiangbei High School?

"It looks like it's finished!"

"It's amazing, it's only been an hour and a half, and I've finished the three questions?"

"It is worthy of being one of the top 20 schools in the country, and the contestants really have a level. ”

"Are they going to take first place again this year?"

Not only Xiao Jun, but other participating groups also saw this situation.

I saw that after the two people from Jiangbei High School finished writing the test papers, they looked at the players around them with a smile on their faces, and their faces were relaxed.

As for those groups who couldn't come up with a solution to the problem after thinking and meditating, cold sweat broke out on their foreheads when they saw this gaze.

You think, you don't even have an idea for the first question, and they've already done all three questions. What's that experience?

Invisibly, the players present who have not yet completed all the answers are all under invisible pressure.

"Originally, I wanted to ask the Xueba in the Xueba chat group to help solve the problem. But seeing that Yang Qianqian seems to be okay, I'll just hold my ground for now. I'll go out when she really can't answer it!" Xiao Jun said secretly in his heart.

With the [Xueba Chat Group] hanging up, he has no problem answering the question even if he has half an hour left!

What's more, this time the exam was 4.5 hours, and now it has only been more than an hour.

In the blink of an eye, it was two hours.

The second group of contestants finished writing, and it was the high school attached to Jiangbei University! Although it was half an hour slower than Jiangbei High School, this efficiency was also against the sky. Because the reason why the Olympiad questions give you so long to do the questions is because sometimes you often think hard and meditate for 2 hours without necessarily having the idea to solve the problem, or even unable to do it!

In the examination room, the contestants from these two schools stared at the other contestants with a smile on their seats after they finished writing, making those contestants who came into contact with their eyes sweat coldly!

That is, at this point when the exam was conducted for two hours, Yang Qianqian had already begun to solve the third question!

"Originally, I thought that the last question needed me to come out, but I didn't expect Yang Qianqian to be able to solve it by herself. When Xiao Jun saw this, he secretly said that he had indeed won today.
