Overnight, another weekend passed, and the new week came instantly. In the morning, Gu Chen realized that the sky was pressed against the heavy dark clouds. It seemed that it was going to rain.

Finding thick clothes from the closet and putting it on, he immediately felt warm.

At this time, the guys climbed up one after another.

Gu Chen looked out of the window and a tree that was about to fall downstairs in the bedroom, and said with a smile: "Winter is here!"

"I'm going, it's so cold!"

As soon as Peng Jiawei drilled out of the quilt, he felt a coolness, and he called quickly.

So everyone took out thick clothes and put on it, and couldn't help sighing why it was suddenly cold.

Especially Cao Lei, a big fat man, after putting on thick clothes, it feels like a dumplings.

Today is just November 1st. If it is in the north, it will be heated in half a month.

But in the south of the Huaihe River, the north and south of the Yangtze River, but there is no such good luck.

For people in this part, in winter without heating, it is almost frozen to die.

And Jiangcheng is just in this place. Every winter, there are snow every winter. The temperature is still there for many days.

Therefore, for students like Gu Chen, two thick quilts must be covered in winter, otherwise they cannot protect the cold at all.

Because I drank alcohol last night, Gu Chen didn't run.

Looking at this cold weather, he felt that if he was running behind, he had to give great perseverance.

The best way is to buy a treadmill and run indoors.

So he thought of the house again.

Yes, the house.

Hey, why do you always think of the house? He suddenly wondered again.

During this time, it seems that the number of times I want to do the house is a bit more.

But thinking of the house, he sighed again.

The house prices in Jiangcheng are still cheaper, but the houses near Nanhu, less than 200,000.

The money in his pocket is full of 200,000, of course, it is impossible to buy a house.

It seems that buying a house at least has to wait until next year.

Just like this with the three people in the bedroom, came to the cafeteria for breakfast, and then came to the classroom.

Today is a professional course for computer, "Data Structure" of the basic course of the university.

This is a theoretical course. The teacher's surname is Li. He is a respectable old professor.

He can be said to be the earliest domestic programmers. He once also wrote the operating system by himself.

Therefore, everyone admires this teacher.

In Gu Chen's memory, this teacher Li is generally rarely named. The appearance looks kind and speaks well.

But don't be confused by superficial phenomena. This teacher is amazing.

He does not name it, but a name is a key battle to determine whether it is or not.

Therefore, even after more than ten years, he is still very impressed by this.

Everyone knows that a course is generally synthesized by the test scores and flat scores.

Of course, this ratio is different for each school and majors, so it cannot be generalized.

Some courses are not important, and the teacher is very good to speak. Even if you often skip class, you will pass you at the end of the period.

However, some courses are different. The teacher is strict and very strict with the class. This is very high.

And the strategy of this teacher is that you usually don't name it to relax your vigilance, but in a certain class, you will give you a sudden attack.

But if you think it is okay to name it once, and you can come later, then you are wrong.

Because this time is the only name for his semester.

In this case, a lesson determines your usual grades.

In this case, the person who did not come was really miserable.

Because of the negligence that did not come at a time, it caused a hook, and it was too late to cry in the end.

It was for this reason that Gu Chen did not escape from the old professor's class.

And he also said to the three people in the bedroom. It does n’t matter if other lessons, you must not escape.

Because you don't know whether he is named at that lesson, and he doesn't know if it is named or after class, so you can't predict in advance.

Several people came early today, and there were not many people in the classroom.

So Gu Chen chose a position in the middle, Cao Lei, Peng Jiawei sitting right away.

As for Li Li, he ran to the second row. For a good student who loves learning, this is a good position.

Of course, the first two or three rows are also the positions of girls in several classes.

For others, they do not take care of the positions here, but girls like them very much.

It is also possible for this reason that among the top ten of the four classes, half of the top ten girls account for more than half.

You know, there are only twenty girls in four classes, but there are nearly one hundred boys.

But ironic is that there are few girls who are programmers after graduation, and fewer people enter large companies.

Therefore, girls are more than learning, but the real programming is still the advantage of boys.

After a while, the old professor Li wore glasses, walked up slowly, and then sat on the podium.

Because of physical reasons, the school deliberately approved Teacher Li to sit on a lecture.

In fact, his situation can be retired in advance, but he still insists on teaching positions, so everyone still admires Mr. Li's morality.

After the ringtone of the class, Teacher Li saw everyone quiet, then turned on the computer and started playing PPT.

Seeing that Mr. Li had no other actions, Gu Chen understood that he would not be named today.

It is really that Mr. Li does not name it a day, which is like a sword hanging on his head, making Gu Chen shocked.

Looking at Teacher Li's lecture, Gu Chen recalled the course of the data structure.

For this course, it is actually very basic and very important for students in computer majors.

If you learn well, you can dig into data in the future. The algorithm engineer is developed. The prospects are good and the salary is high.

Compared to the development engineers who have dealt with products and business, it is relatively simple to do algorithms.

Gu Chen did not have a few and the products in the last life, and the demand was changed again and again.

From the online paragraphs, such as the development of a picture of a kitchen knife to cut the product, it can explain how bad the relationship between the two sides.

There are often quarrels, and even fighting is possible.

"Gu Chen, call you."

Just as Gu Chen was in a daze, Cao Lei next to him took a picture of him.

Gu Chen returned to God, so unknown: "What?"

Cao Lei muttered and whispered: "The teacher calls you to answer the question, you can stand up quickly."

I went and called him to answer the question. He didn't know if he just left.

At this time, Gu Chen also found that everyone looked at him, and Mr. Li on the podium also looked at him.

So, in the eyes of everyone, Gu Chen slowly stood up.

Teacher Li said: "Classmates, are we just talking about, are you clear?"

Seeing the PPT on the podium, Gu Chen was speechless. I knew a fart. I just walked away just for a while.

But he nodded and replied: "Teacher, I heard it clearly."

Hearing Gu Chen's affirmative answer, the old professor laughed, and then continued to ask: "Then you answer, what is the difference between the stack and queue?"

At this time, everyone laughed.

After all, from the current situation, Gu Chen was obvious, but they wanted to see how Gu Chen answered.

Li Li, who was sitting before, saw this, and couldn't believe how Gu Chen answered.

Seeing that everyone looked at the lively expression, he was calm. On the one hand, he quickly recalled the content of the memory. On the other hand, he looked at the PPT on the podium, and then began to organize his own language.

Gu Chen knows about the stack and queue. After all, every time he changes the job, he will review the test questions.

在李老师有点戏谑的目光中,只见他缓缓说道:“栈和队列都是比较常用的数据结构.栈的特点是先进后出,而队列则是先进先出……另外,两者的

The operation limits are also different. The queue is in line at the end of the team, and the stack cannot operate the bottom of the stack ... There are also different data speeds traversed by the two ... "

Hearing Gu Chen's answer, Mr. Li's expression was surprised.

Immediately nodded slowly, obviously Gu Chen said very correctly.
