Xueba starts with change

Chapter 202 Arranged like a tower?

"Let me give you a head start, unity is strength, sing!"

The students of the 7th company followed the instructor's command and began to shout at the top of their voices: "Unity is strength, unity is strength, this strength is iron, this strength is steel, harder than iron, stronger than steel..."

When the 7th company finished singing, the female soldier company naturally began to fight back not to be outdone: "The red sun shines all over the east, and the God of freedom is singing with all its heart..."

I have to say that the singing of the female soldiers is much better than their 7 consecutive roars.

But it sounds good, but it doesn't mean you can win.

The 7th company started the second military song: "Forward! Forward! Forward! Our team faces the sun..."

Following the three forward sounds, the 7th company also fully raised its momentum, and the sound was even louder than before.

In the team, Chen Zhou, who was infected by the atmosphere, also blended into it and sang loudly.

The female soldier company also came up with a song "Return from Target Shooting".

But this song obviously doesn't have the momentum of Chen Zhou and his 7th company.

For some reason, Chen Zhou suddenly thought of a song, and hummed to himself: "The smoke rises, the mountains and rivers look north..."

And the people of the 7th company, no matter who started it, immediately roared together.

The song "Serve the country with loyalty" is full of momentum!
And the purpose of the 7th company is to overwhelm the female soldier company on the opposite side!
The evening training is over, when the instructor checks the dormitory.

In Chen Zhou's dormitory, he patted Chen Zhou's shoulder with a smile: "Good job!"

Chen Zhou smiled awkwardly. He really didn't expect that such a small voice could be heard by this group of people.

"Everyone! Stand at attention, turn right, and run! Target, right in the middle of the playground!"

Following Bai Bing's password, the students of the 7th company began to run in the middle of the playground.

Chen Zhou couldn't help muttering, what's going on?
It wasn't just Chen Zhou who didn't understand, the students of the 7th company didn't know what Instructor Bai was going to do.

"Standing!"

"To the left!"

"Take a break!"

"Arms outstretched, arms apart!"

In the middle of the playground, the 7th company who came here followed Bai Bing's password and began to deploy the team.

"Today, I will give you a special phalanx training!" Bai Bing cleared everyone's doubts with one sentence.

"Chen Zhou!"

"To!"

"Take a step forward!"

"Wang Tao, Xiong Kang, turn back! Take a step forward! Turn back!"

……

Just as Chen Zhou was puzzled, the white soldiers gave out passwords one after another, and the formation of the entire team began to change!
"What are you planning to do?"

Doubts came to mind again.

But after all the passwords were issued, Chen Zhou realized after turning around that this is a triangular formation?
It's an equilateral triangle...

Triangular formations are not absent, but this is the first time Chen Zhou has seen them during military training.

Chen Zhou guessed that they might be planning to train their 7th company to change various formations.

Just as Chen Zhou guessed, Bai Bing began to issue passwords again and again.

The phalanx of the 7th company constantly changed the formation according to the password.

Practicing the change of formation is more difficult than usual training.

Moreover, when it came to the triangular formation, Chen Zhou became the top of the team.

It is very prominent.

In the afternoon, the 7th company was so abruptly in the middle of the playground, constantly practicing the change of formation.

When we went to the cafeteria at night, the students from the 7th company complained one by one.

They were too tired after following the password all the time.

After cooking, Chen Zhou and Zhao Qiqi sat together.

Zhao Qiqi looked at the abundant food in front of her, but she didn't have any appetite.

Seeing this scene, Chen Zhou smiled slightly, and it was exactly what he thought.

"Chen Zhou, why do you think the instructor is training us like this?" Zhao Qiqi said out loud.

"Hmm..." Chen Zhou glanced at Zhao Qiqi, "I don't know, why don't you ask the instructor?"

Zhao Qiqi: "Forget it, I dare not ask Instructor Bai, when you didn't watch his military training, he trained those who didn't do well..."

Chen Zhou took a bite of the rice and said, "Then hurry up and eat."

"Chen Zhou?"

"Huh?" Chen Zhou looked suspiciously at Li Li who suddenly called him.

Li Li thought for a while and said, "Speaking of which, when I was practicing the triangle formation, I saw Chen Zhou standing at the front, and I thought of something."

Zhu Mingli also asked suspiciously: "What?"

Li Li: "Pyramid, does Chen Zhou seem to be on the top of the tower?"

Zhu Mingli: "When you put it that way, it's really similar."

Zhao Qiqi: "The top of the pyramid can represent Brother Chen's status."

Chen Zhou smiled: "Is it arrayed like a tower?"

Suddenly, the smile on Chen Zhou's face faded, and he thought of an important thing.

Number Pyramid!
Arrange all the positive integers in the triangular graph, and divide them into the first level, the second level, the third level, until the nth level, the mth level.

The integer corresponding to each level is stored in the triangle.

每一级存放的整数范围是，第一级为2^0到2^1，第二级为2^1+1到2^2，第三级为2^2+1到2^3，一直到第n级为2^(n-1)+1到2^n，第m级为2^(m-1)+1到2^m（m→∞）。

This mathematical model is called the digital pyramid A.

Sparks of thought kept flashing in Chen Zhou's mind.

So much so that his hand holding the vegetables was hanging in the air like this.

The three of Zhao Qiqi were also confused by Chen Zhou's sudden action.

"Brother Chen, what's wrong?" Zhao Qiqi asked in a low voice.

"I don't know." Zhu Mingli shook his head.

"Maybe I thought of something important." When Li Li said this, there was a strange look in his eyes.

"Then should I call him? It's time for evening training soon." Zhao Qiqi looked at the two partners beside her.

Li Li was about to speak when he saw Chen Zhou put his hand down.

"Call me?" Chen Zhou had a look of joy on his face.

"What's wrong with you, Brother Chen?" Zhao Qiqi asked concerned, he was still very worried that Chen Zhou would not be fooled by the military training.

Zhu Mingli also asked with concern: "Chen Zhou, are you okay?"

Chen Zhou smiled slightly, but did not explain, but said: "Let's go, the evening training is about to start."

Chen Zhou never imagined that this military training would give him unexpected gains.

This digital pyramid A is very useful!

During the 14 days of military training, God was very strong, but it didn't rain, and they were all tanned.

With the completion of the formation change of the 7th company, the 14-day military training has come to a perfect conclusion.

The 14th grade undergraduates of Yenching University also completely accepted a military baptism.

When they were about to bid farewell to the military training base, the comrades in the 7th company said goodbye to Bai Bing very enthusiastically.

Looking at the soldier he had been carrying for half a month in one hand, Bai Bing's expression was also a little excited.

Everyone in the 7th company hugged.

Especially when it came to Chen Zhou, Bai Bing gave him a bear hug.

Chen Zhou's performance during military training was particularly outstanding.

The action is done cleanly, neatly, and in place.

This is also the reason why Bai Bing put Chen Zhou on the tip of the triangle formation.

By the way, Bai Bing also praised Chen Zhou: "Good boy, during the training, everyone else was lying down, but you can still be alive and kicking, with good physical fitness!"

Hearing Bai Bing's words, everyone else looked at Chen Zhou.

They also clearly remembered that when they were all lying on the playground exhausted, this mathematics major was the only one standing!
They couldn't figure it out, you spend all day in the library, in the study room, and have a girlfriend, how can you have such good physical strength?
