I really don't want to lie down and win

is it hard?

The calculation process is not difficult at all, but it is quite a test of mathematical skills and skills, and there are traps everywhere. As long as there is a problem in one step, then this problem is unsolvable... Mathematics is so cruel and rigorous, and this problem ...sublimated this core.

"Great!"

"Unexpectedly, such a question contains so many test points!" The oldest teacher couldn't help but sigh with emotion: "I am completely convinced...His level is much higher than Teacher Ge and Teacher Tao. .”

words fell,

The professor rushed to Zhang Ju and asked: "Zhang Ju...can you tell us who this questioner is? I want to communicate with him and learn from other places. There is no one with this level of questioning. I can never think of such a question..."

Hearing the old man's words, Zhang Ju showed a helpless expression, and said, "This person... can't mention it. In short, do you think this question can be placed in the last question of the mathematics test paper for the college entrance examination? Do you think so? Is it too difficult?"

"Ok!"

"The difficulty is indeed too high. I bet... Once this question is asked, there should not be many students in the country who can solve it." The old man said: "We can only reduce the difficulty a little...Of course it is fine. , After all, it is used as a touchstone, you can check how many math geniuses there are among the students who take the college entrance examination."

actually...

Mathematics geniuses never need to take the college entrance examination, because this kind of people have already been admitted to prestigious schools in advance, and those who take the college entrance examination are not geniuses, it is very cruel... But this is the status quo, and of course there are accidents, such as Xu Mang... . He took the college entrance examination, but he had already received invitations from many schools.

"That's fine!"

"I don't want to bother him anymore, just follow this topic." Zhang Ju said: "I will leave the rest to you."

words fell,

Zhang Ju left in a hurry.

At this time, several people at the scene began to talk about the mysterious questioner, saying that everyone has it, but no one can be recognized by the presence. At this time...someone proposed a certain legendary figure, he is Xu Mang.

"Huh?" A young man said, "Could it be Academician Xu?"

"Academician Xu?"

"Is it Xu Mang?" The very old special-grade teacher was stunned for a moment, thought for a long time, raised his head and said seriously: "Don't tell me... I really doubt it. This topic was written by Academician Xu. Only he can come up with such a title."

"How about... Let's look for the college entrance examination papers from that year and see what the gap is between the two, and then we will know." The young man said, "I remember... four or five years ago It’s the paper, there should be a full version online.”

Subsequently,

The young man began to search for the contents of the exam papers that Xu Mang had published back then. I have to say... the power of the Internet is impressive. In less than a few seconds, more than N so-called complete exam papers appeared. There is a standard answer, and the comments on the Internet are also one-sided. It is simply hellish to say that it was difficult back then.

Then,

Comparing the two, it is not difficult to find that there are many similarities. The central idea is to examine the students' logical thinking ability. If this point is not passed, it is basically cool, and logical thinking ...It was already Xu Mang's specialty.

Many examinee teachers called this type of problem Xu Mang's math problem. Its harsh logical thinking, coupled with the rigorous process, and the final hopeless difficulty were the highlights, ravaging the hearts of the majority of students with impunity.

"That's right!"

"This must be the topic proposed by Academician Xu!" The young man said, "I can swear..."

"It's no wonder Bureau Zhang is so secretive. It turned out to be from the hands of Academician Xu... It's too scary. The college entrance examination students in Zhejiang Province have already felt hopeless. Now it's the turn of the whole country... This exam is too difficult." The oldest teacher said helplessly: "Fortunately... it's just a touchstone, otherwise..."

"Wait a moment!"

"I think Academician Xu must have lowered the difficulty." Another teacher said: "It is undeniable that this question is difficult, but the difficulty is a little easier than the last question in the Zhejiang Provincial College Entrance Examination math paper, so I decided to lower it. difficulty."

Speaking of which,

The teacher said with emotion: "I really want to know what the original version was like."

original version?

know what it does?It's just self-defeating.

...

magic city,

Xu Mang was lying on the sofa, enjoying a rare leisure time. Today, the two little devil kings were picked up by his mother-in-law, and Xu Mang simply didn't go to the research institute, just stayed at home to play games. Recently, on the G fat game platform, A pirate game appeared, and Xu Mang was a loyal fan of it.

Fun is fun, but he relies too much on his teammates, and Xu Mang is the kind of handicapped party who is often disliked by others, so he simply built his own fleet, recruited a bunch of great players online with money, and explored the mysterious sea .

"Hey?"

"Second grandpa...I'm at home." Xu Mang received a call from his second grandpa, and asked curiously, "What's the matter? If you let me solve the problem... I'm sorry, I don't have time right now, little Man's Materials Research Institute is about to be completed, and I'm still worried that there will be no one there."

"I want to ask you something."

"Why did the United States announce a list of sanctioned entities?" Second Grandpa asked seriously: "Many of our top universities are all covered. What is going on?"

"what?"

"Why don't I know?" Xu Mang was taken aback for a moment, and his tone became a little hurried, and he said, "This...when did this happen?"

"yesterday!"

"It was announced yesterday." The second grandfather said: "If this list is true, then we may be greatly affected. Do you think this is because we forcibly entered the Council of the World Organization for Science and Development? Sanctions?"

Not to mention,

Xu Mang also decided that way. The United States was worried that Huaguo would enter a stage of rapid development because of the previous incident, so it deliberately imposed sanctions.

certainly...

At present, it is not sure what is going on, and it is not easy to judge directly.

"I'll check the list first and call you later," Xu Mang said.

After hanging up,

He hurriedly ran to his study, turned on the computer and searched the relevant list on the Internet. A total of ten colleges and universities were included in the sanctions list, but there was also a little surprise that top universities such as Tsinghua University and Beijing University were not included in the list.

But it's normal,

Because the above schools can be analyzed that the United States intends to block technical talents in Huaguo, because these schools cover a wide range of fields, such as computers, artificial intelligence, engineering, materials, big data, electronic information, etc., are all The latest cutting-edge subject direction.

hatred!

What a fucking hate!

What are they trying to do?

Xu Mang fell into deep thought. Although the Internet was full of applause, thinking that there are so many awesome universities in Huaguo that can be included in the list of the United States, Xu Mang felt a little worried. There has always been a question...

Some of its core technologies have been restricted by the United States for a long time. If some technologies are suddenly curbed at this time, then... some disciplines will be finished.
