Chen Fan Is Number One? (Seeking Support)
Chen Fan accompanied Ye Lulu and Zhou Ziqi with a perturbed heart. Ye Lulu was very happy to hear Zhou Ziqi cry.
According to Class Monitor Zhou Ziqi, this question should be very difficult. In that case, no one would get a high score. If they couldn't get a high score, then wouldn't their zero score be justified?
It was perfect.
"Aiya, class monitor, don't feel bad. What if you get first place with eighty or seventy points?”
"Yeah, I've thought about that, but it's my first time not getting full marks in Mathematics. I can't accept it.”
"Look at me, I have so many zeros.”
Zhou Ziqi and Chen Fan looked at Ye Lulu at the same time. Forget it, there was no point in talking to her.
This guy was completely hopeless.
Chen Fan suddenly sneezed and rubbed his nose.
Ye Lulu looked at Chen Fan and said,"What are you doing?" Are you confused or something?"
"No, I feel like someone is talking about me behind my back.”
Ye Lulu chuckled and said,""Other than a beautiful woman like me who would be willing to chat with you, do you think anyone else would miss you? It's probably a man."
Chen Fan ignored Ye Lulu, who was always looking down on people.
At this moment, in the Mathematics team, the teachers were marking the papers helplessly.
This batch of papers was very fast because most of them were empty.
The answer to the big questions was basically known by just looking at the beginning.
"How many marks did you get for this paper?"
Someone asked Mu Wanqing. Mu Wanqing tied her hair up with a black headband, then found her own paper and handed it to her peers.
"If it were two hours, I would probably get more than 90 points. Moreover, I used some of the knowledge points from university, such as the geometric sequence. I don't think I can do it purely based on high school knowledge.”
"You're a little better than me. I estimate that you'll only get around seventy marks. The time is too short. Normal Mathematical Olympiad papers start from five hours.”
"Are there any good results on your paper?”
"No, I haven't."
Mu Wanqing and her peers sighed at each other. This paper was really too difficult for these students.
The team leader rubbed his head and looked out of the window. He was probably very helpless.
Everyone present was a math teacher. They all understood one thing. Math was not something that could be achieved by just hard work. Math was a true 99% talent and 1% hard work.
Which teacher wouldn't want a math genius among their students?
Who wouldn't want their students to be famous in the Mathematics exam?
"Have the scores been tabulated?"
Everyone looked at each other without saying anything.
"How about this? Those below ninety points won't be counted.”
90 points?
Mu Wanqing said," If it's divided according to passing, then I don't think anyone will pass. This paper is too difficult."”
"Is there really no one?"
At this moment, a teacher raised his hand and said,"There was one person who passed.”
There was a passing grade?
"Give me the paper," Huang Youwei said.”
The paper was handed to Huang Youwei. Huang Youwei looked at the name and said,"Chen Fan? Which class is this student from?"
Mu Wanqing was stunned for a moment and said," If I'm not mistaken, he should be in my class. But he usually passes. Did he pass again this time?"”
Huang Youwei looked at the questions one by one.
The papers were surprisingly clean. There were no traces of correction. He got six multiple-choice questions right and three fill-in-the-blank questions right.
He got two of the geometry proof questions right.
He got a function question right.
Exactly ninety points.
"Something's wrong. Something's wrong with your student. Something's very wrong.”
Of course, something was definitely wrong. The only ninety points meant that this person was first.
The cheating guessing game is played between two players A and B. The game relies on two positive numbers K and N that both A and B know.
At the beginning of the game, A first selected two numbers x and N, 1xN. A told B the value of N truthfully, but kept X a secret. B now tries to get information about x by asking questions in the following way: Every time B asks a question, B chooses a set S consisting of a number of positive numbers (the set used in the previous question can be reused) and asks A if x belongs to S?. B can ask any number of questions. After each question from B, the host must immediately answer yes or no to B's question. A can lie, and there is no limit to the number of times he can lie. The only limit is that A must answer the truth at least once in any k 1 consecutive answers.
After B has asked all the questions he wants to ask, B must point out a set X that contains at most n positive numbers. If X belongs to X, B wins; Otherwise, A wins. Prove:(1) If n2k, then B can guarantee victory;
(2)For all sufficiently large numbers k, there exists a positive number n1.99k such that B cannot guarantee victory.
"You all remember this question, right?”
Everyone nodded.
"What algorithm is used for this question? You guys tell me."
"I think it should be calculated using a sequence of numbers," said Mu Wanqing.”
Sequence?
"Sequence of numbers, my ass. Your thinking isn't good enough. This question, this guy's algorithm is very novel, so it's normal for you to deduct points. This child used a binary-based algorithm. To put it bluntly, it's something from the computer that was applied to mathematics. But what's interesting is that when he wrote the answer at the end, he got it wrong.”
What could he think of?
Everyone was puzzled.
Huang Youwei said," It means that this child can get it right, but it's not necessary. Moreover, the rest of the questions, the steps, and the starting line of thought are all correct, but he didn't write the final answer correctly. What's even more interesting is that this child has other ideas for this question, but he restrained himself. However, I still saw traces.”
"Leader, what do you mean?" Mu Wanqing asked.”
"I feel that this child might be controlling his points. I hope it's just my guess.”
Everyone was shocked.
