[I decided to study mathematics well, and I want to continue to make our national flag appear on IMO!]

[The wisdom of young people will make the country wise, the richness of young people will make the country rich, the strength of young people will make the country strong, the independence of young people will make the country independent, the freedom of young people will make the country free, the progress of young people will make the country progress, if the young people are better than Europe, the country will be better than Europe, and the young people will be more powerful than blue.

The star is more powerful than the blue star! I have never believed as much as I do now that our mathematical community in Xia will definitely get better and better in the future! Return to the world's first-class level!]

Norway, the awarding of silver and bronze medals has ended. Jeff Roland returned to the podium. He smiled and said: "Next, we will also award a special award."

"I believe everyone has noticed that one of the gold medal players this year received the special honor of 70 (1 point). Why do I insist on awarding him this special honor that has only appeared once in history? Please watch the big screen

!”

Two answer sheets filled with the solution process were immediately projected on the big screen.

"In this competition, we were surprised and even incredible to find that there were two answer sheets, which used five different solutions to each question, and each solution was very innovative. The longest solution

The steps for the question don’t exceed ten lines!”

Countless uproar and exclamations immediately erupted from the audience.

The number of questions, difficulty, and innovation requirements of this IMO can be regarded as the highest in IMO history. Even last year's champion, the talented player Hill of the American team, could not come up with a second place in any question.

A solution.

But now it is actually said that some candidates have solved all the questions using five new solutions?

"We will put these two answer sheets on the official website for everyone to download and study. Yes, study. I believe that anyone who studies it seriously will learn many new Mathematical Olympiad concepts from it! Because these fifty solutions, behind

It’s the same scientific and efficient Mathematical Olympiad theoretical system!”

The projected screen switched again, showing a transcript of 70 1, as well as an English comment on the transcript——

"The future of IMO will usher in new changes and developments because of the new thinking model shown in this candidate's answer sheet!"

Jeff Rowland pointed at the screen and said: "This is a comment written by me. After our nearly two days of searching and verification, we have determined that this is a brand-new theoretical system that has never appeared in the world. Its creator is most likely a
