Zhang Zhongyuan looked a little subtle, and waved his hand and signaled Chen Zhou to sit down.

Now, I snatch my own words again...

After Chen Zhou sat down, he looked at Zhang Zhongyuan with interest.

He didn't think that as others said, Zhang Zhongyuan had nothing to say.

As expected.

Zhang Zhongyuan coughed lightly and said, "Student Chen Zhou has explained the significance of the sequence verification method in detail, and also gave examples to illustrate the defects in it."

"But, if there is a flaw, it does not mean that it has no meaning to study."

Zhang Zhongyuan's words also attracted the attention of all the students again.

Seeing this, Zhang Zhongyuan smiled slightly, turned around and wrote a few words on the whiteboard [Ignore even numbers and do not record].

However, for some reason, when he was writing these words, he suddenly thought of the topic discussion when Chen Zhou first participated in the topic.

Depressing this inexplicable idea, Zhang Zhongyuan turned around, looked at Chen Zhou first, and then continued: "Class Chen Zhou's example just now is the general term for even numbers. If we ignore even numbers, only for odd numbers, through

What about verification methods?”

When he heard Zhang Zhongyuan's words, except Chen Zhou, the other students fell into thought.

Zhao Qiqi beside Chen Zhou even turned his head and asked Li Li: "If you simply verify the odd numbers, it seems to work?"

Li Li didn't say anything, but just walked over Zhao Qiqi and looked at Chen Zhou.

Chen Zhou naturally knew this new verification method, but it also had flaws.

Chen Zhou was looking at Zhang Zhongyuan all the time, hoping to see Zhang Zhongyuan give different ideas.

Zhang Zhongyuan picked up the wolfberry soaked on the table, took a sip, and looked at the time.

It was just enough time for him to finish this part of the content and then spread the ideas of his classmates.

Covering the cup lid and putting the quilt on the podium, Zhang Zhongyuan said: "Simply starting with odd numbers, you need to consider the first odd number to be verified."

"It may be an odd number that can be divisible by 3, or an odd number that cannot be divisible by 3. However, after 3x1, the second odd number reached, as well as the third odd number, the fourth and fifth,

Wait. Every odd number that reaches the entire process must not be eliminated by 3."

"However, if all verification starts from odd numbers that can be divisible by 3, every odd number that arrives in the hail course must not be eliminated by 3, and ultimately it can be attributed to 1, then all odd numbers must be traversed."

With Zhang Zhongyuan's narration, the thoughts that the students had just been pulled back were once again trapped in thought.

Chen Zhou was still looking at Zhang Zhongyuan. He knew all these contents, and he was still waiting for Zhang Zhongyuan to say what he next.

However, Zhang Zhongyuan obviously seized the time and did not immediately interrupt the students' thinking.

Chen Zhou felt someone touched him, and he turned his head in confusion and looked at Zhao Qiqi.

Zhao Qiqi asked in a low voice: "Brother Chen, what does traversal mean?"

Chen Zhou was slightly stunned and immediately explained: "Traveling is the concept of discrete mathematics, which refers to visiting each node in turn along a search route, which is what Professor Zhang said to arrive. Well, in his sophomore year

This content is included in the book "Data Structure".

"Oh." Zhao Qiqi nodded repeatedly, a little ashamed.

He hasn't seen this textbook yet...

Chen Zhou's answer also explained to other students who didn't know how to traverse the word.

Naturally, they turned their heads and looked at Chen Zhou again.

There is admiration and envy in the eyes.

Although I know that Chen Zhou is already a person who takes the final exams of each grade of the mathematics department, it is a different feeling to truly feel this powerful strength.

On the podium, Zhang Zhongyuan looked at the time and said again: "I just mentioned odd numbers that can be divisible by 3. I believe you have thought of odd numbers that cannot be divisible by 3."

"If all verification starts from odd numbers that cannot be divisible by 3, then every odd number that arrives in the hail journey will never be eliminated by 3. They are ultimately attributed to 1."

Speaking of this, Zhang Zhongyuan looked at Chen Zhou again before continuing to say the following words: "In fact, in the verification process, odd numbers that cannot be divisible by 3 have infinite numbers in the previous step.

”

"Among them, about 1/3 of the proportion are odd numbers that can be divisible by 3, and about 2/3 of the proportion are odd numbers that cannot be divisible by 3. And what do you think about this phenomenon very similar to?"

As soon as Zhang Zhongyuan finished speaking, Chen Zhou stood up and said, "It's very similar to the situation of natural numbers."

Hearing Chen Zhou's words, Zhao Qiqi next to him suddenly realized: "Yes, it's very similar to natural numbers, why didn't I expect it?"

Li Li glanced at Zhao Qiqi: "Do you want to know why?"

Zhao Qiqi: "Why?"

Li Li: "Because you don't read more books than him."

Zhao Qiqi was stunned and didn't understand the meaning of this sentence. He muttered: "You might as well say that I'm not as smart as Brother Chen..."

Li Li glanced at him and stopped talking.

On the contrary, the classmate in front of Zhao Qiqi turned around and looked at him with complicated eyes and said, "I think that's what he meant..."

Zhao Qiqi: “…”

Zhang Zhongyuan raised his hand to stop the noise, then signaled Chen Zhou to sit down, and he took back what he said: "What Chen Zhou said is right. This phenomenon is surprisingly coincidental with the situation of natural numbers."

After saying that, he noticed that Chen Zhou was still standing there and asked, "Chen Zhou, do you have any problems?"

Zhang Zhongyuan's words also brought all the students' eyes over.

Under the gaze of everyone, Chen Zhou whispered: "Professor, this new verification method has obvious flaws."

Zhang Zhongyuan nodded with a smile: "Well, tell me?"

Zhang Zhongyuan’s idea at this moment was that this kid was all in the limelight.

However, he didn't care.

After all, Chen Zhou has always been a student he values ​​very much.

What's more important is that this kid looks very similar to the young him...

Chen Zhou didn't think so much and said directly: "The operation of this verification method is discontinuous, and it is very troublesome in verifying the climb or descending process. When climbing, you need to factorize the 2, and when you descend,

You need to calculate the n-power of 3 first."

After a pause, Chen Zhou continued: "Of course, this method also has advantages. The advantage is that when it reaches a near infinite climb, it can be replaced directly. Well, let me give you an example."

When Zhang Zhongyuan heard Chen Zhou say that he gave an example, his brow jumped, and he thought of the first discussion of the topic.

At that time, Chen Zhou also gave an example to supplement Shen Jing's research ideas...

However, Chen Zhou's voice brought Zhang Zhongyuan's thoughts back to the classroom.

"For example, the verification process of multiplying 2n-1 by 2 by 100 million power, is to replace 100 million 2 with 100 million 3, that is, multiplying 2 by 2n-1 by 3 by 100 million power, and then subtract 1 by 100 million power, which is to replace 100 million power, which is to replace 100 million power, which is to replace 100 million power, which is to replace 10

, Through one-time replacement, we need to calculate the power of 300 million."

"If you follow the traditional verification method, you need to multiply 2n-1 by 2 to 100 million to calculate the power of 100 million, and then calculate the step of 100 million to 1 to get this result."

When Chen Zhou finished speaking, the bell ringing outside the classroom rang.

Zhang Zhongyuan looked at the time and it was almost done. Chen Zhou's performance was over and he could be finished...
Chapter completed!
