"Click here, click here......"

"There's only one empty seat left, what should I do?"

"There's another one here!"

"Oops! It's over again......"

Song Xingye sat in front of the computer, and Tang Lingfei stood next to him and kept coming up with ideas. In the past half hour, the two girls took turns holding the mouse and happily playing the game made by Xu Zhe.

But half an hour has passed, more than a dozen times have died, and the customs clearance is still far away.

As soon as they started playing, they realized that the game was harder than the usual Lianlianguan these days. But they really didn't expect that the difficulty would be so high.

Song Xingye put down the mouse, stood up and asked, "Can this game really be cleared?" ”

Xu Zhe, who stood there with his back against the windowsill and watched the excitement: "I don't know." ”

Tang Lingfei: "This is a game you made, you don't know it?" ”

Xu Zhe: "How these squares are arranged in each game are randomly selected by the system, of course I don't know. ”

Song Xingye finally realized a problem: "Is it possible that this game can't actually be cleared?" ”

Xu Zhe smiled: "It's possible, because I haven't done a good job of the detection mechanism so far." ”

Song Xingye: "Detection mechanism? ”

Xu Zhe: "Every game is random, it's like ...... How to put it, it's like a computer automatically generates a maze for you, randomly generated. As for whether this maze can be passed, the computer does not know. ”

Tang Lingfei was suddenly indignant: "Then didn't we waste half a day's work in vain?!" ”

Xu Zhe spread his hands: "I just said that I would let you try this game, and I didn't say that I would definitely be able to clear it." The reason why it is still a semi-finished product is that I can't guarantee that it will be able to clear customs. ”

As long as he has seen the finished product in advance, it is not difficult for a programmer with some experience like him to make the prototype of this game in a period of time. But to make sure you can beat most of the time, you need more complex logic. And Xu Zhe has not done anything similar before, so it is naturally difficult to straighten out his thinking.

Tang Lingfei sat down again and started a new game.

Song Xingye reminded: "Fei Fei, are you still playing?" Xu Zhedu said that this is probably not possible to play at all. ”

Tang Lingfei: "I don't care, I just want to play!" ”

Xu Zhe: "Up? Tsk, that's right, this game is meant to achieve such an effect. ”

Tang Lingfei continued to play regardless of it.

Song Xingye asked, "Do you want to post this game online?" ”

Xu Zhe shook his head: "This demo is actually just used to practice. This game may be sent out in the future, but not now. Because now there is no interpersonal environment for mobile Internet. ”

Song Xingye: "...... What do you mean? ”

Xu Zhe's meaning would be easy to understand if it was placed ten years later. Because there is no V letter now, there is no way to get viral transmission by forwarding. And when it comes to the quality of the game, it's a bit far from other alternatives.

"What I'm preparing for now, and what I'm going to do in the summer, is actually this game."

As he spoke, Xu Zhe picked up a draft book on the table and handed it to Song Xingye.

The girl flipped through it and said suspiciously: "The target platform, Pingguo Store; The name of the game, Cutting Fruit...... What is this? ”

Xu Zhe smiled and said, "You'll know when I make it." ”

At this time, Tang Lingfei's new game was gone. She stood up angrily: "Don't play, go back to study!" ”

Xu Zhe picked up the book "Introduction to Algorithms" and returned to Tang Lingfei's house with them.

In Tang Lingfei's bedroom, the three of them still sat down like that - the main person who was tutored sat in the middle, Song Xingye and Xu Zhe left and right.

At this time, it was Song Xingye's turn to tutor, so Xu Zhe took the book and read it. Looking at it, he also used his pen from time to time to outline the key points.

Song Xingye suddenly asked: "Does this introduction to algorithms have anything to do with making games?" ”

Xu Zhe: "Yes. After you really start to do a lot of things, you will find that there are too many links that you need to make up and improve. ”

One Thursday morning, Mr. Zhao was talking on the podium when he suddenly stopped and sighed.

Then he changed his tone to a casual tone: "I found out, I can't go to the first class." No one was listening to the first class every morning. Why don't I give a lecture and just play a lullaby for you, right? ”

The students finally reacted a little – they gave a sparse laugh.

Teacher Zhao knocked on the lectern: "Cheer up!" I'll stop for a moment to see who's still dozing, and I'll let you sleep enough. ”

The strange thing is that many of his classmates couldn't help but doze off when he was lecturing, but as soon as he stopped talking, those students who were supposed to nap suddenly woke up again.

Teacher Zhao stood there, his eyes scanning the audience. Suddenly, he noticed that there was a man in the first row closest to the lectern who was not listening to the lecture but was not napping.

That's Xu Zhe. He was working on the question, but something seemed wrong with what was written on the scratch paper.

Teacher Zhao stepped down from the podium, came to him, and glanced down.

Xu Zhe didn't notice the teacher's arrival, and was still writing to himself.

Song Xingye, who was at the same table, quietly touched his arm with the tip of his arm.

So Xu Zhe reacted, and then stopped writing.

Teacher Zhao took a deep breath of cold air and asked in a low voice, "Linear algebra?" ”

Xu Zhe: "That's right. ”

Teacher Zhao: "Why are you learning this?" ”

Xu Zhe: "Learn to play." ”

Teacher Zhao: "......"

Xu Zhe: "That's it, teacher, do you have any final mock papers or test papers there, give me some for me to brush, which can be regarded as entertainment and relaxation after learning linear algebra." The more difficult the question, the better, and I won't do the easy ones. ”

Teacher Zhao: "......"

Xu Zhe raised his head and looked at him: "Isn't it?" ”

"Okay, of course, I'll send you back."

Teacher Zhao returned to the podium, looked at the group of first-year junior high school students who were stumped by binary equations, and sighed deeply:

"The gap between people and people is really bigger than the sky."

After class, Wen Hao came to Xu Zhe's desk.

At this time, Xu Zhe stood up, but Wen Hao, the kid, actually pressed his shoulder and pushed him back to his seat.

Xu Zhe: "What are you doing?" ”

"Sit, sit down."

Wen Hao rubbed his hands together and bowed seriously.

Xu Zhe: "? ”

Seeing that his old friend looked puzzled, Wen Hao explained: "You are really too good at pretending to be B, even Mr. Zhao was pretended to be stunned by you, and it is not okay to be unconvinced." Really, surrendered under it. ”

Xu Zhe couldn't cry or laugh: "You pressed me here to say this?" ”

Wen Hao said sincerely: "Teach me how to pretend to be B." ”

Xu Zhe: "Simple, go and learn mathematics." Those who finish junior high school learn high school, and those who finish high school learn calculus and linear algebra. ”

Wen Hao: "Can't learn, is there an easier way to pretend B?" ”

Xu Zhe: "...... No, why do you have to learn to wear B? ”

Wen Hao: "Because it's very handsome." I've noticed that several girls are looking at you wrongly. ”

Xu Zhe: "If your goal is to attract girls, then it is better to practice basketball, which is definitely more efficient." ”

Wen Hao: "The problem is that I can't do basketball." ”

Xu Zhe thought about it seriously and held back a sentence: "Why don't you practice rapping?" ”
