Back in the office, Luo Sanyang stretched his waist, probably because he was middle-aged, and recently found that his waist hurt a little!

I found an old Chinese medicine doctor for acupuncture several times, and each time it worked for a few days after doing it, and then it recurred.

According to the introduction of the old Chinese medicine, acupuncture is effective, but the back pain still has to go through physical exercise to be able to eradicate the root, but it is a pity that as a person who eats with a computer, let him go out to exercise, it is as difficult to accept as a winter swim in the cold winter.

"Is there a candidate for Teacher Luo?"

The office door was pushed open, and Mr. Zhang walked in, the two were about the same age, and they were both computer bigwigs invited by Linjiang Academy.

"Not yet, let's see it tomorrow, what about you!"

"It's almost, but the confidence is a little insufficient, in such a big class, there is only one person who can do AOS exercises!"

"Alone? Wouldn't it be that I still have to find two people on my side! ”

Only one of you, a junior, can do AOS exercises, and even fewer sophomores.

Luo Sanyang shook his head, the computer of Linjiang University itself is not the top in China, and in the case of Shanghai, it is not as good as Jiaotong University.

This time to participate in this kind of international competition, I am afraid that it will also be an accompaniment.

Flipping through the book, Luo Sanyang looked at the small book, a little dazed.

Ay?

What about my AOS exercise booklet?

Take a look at it again, the small exercise book for sophomores is still there!

……

Luo Sanyang slapped his head.

"What's wrong?"

Teacher Zhang asked.

Luo Sanyang looked annoyed: "I should be a little tired recently, and when I gave a classmate a sophomore exercise, I gave the AOS exercise booklet!" ”

"Hey, speaking of which, it's quite interesting to meet that student today, he's a freshman, and he's already started listening to my class, and he's listening to it with relish, the most important thing is that this guy is not from the computer department, but from the biology department!"

"Oh, really?"

……

"Watching the game together after dinner?"

"No, I have to go home tonight!" Bai Zhou shook his head and took the exercises, Bai Zhou still attached great importance to it, after all, the university teacher named him, which was not ordinary.

And after he opened it before, he found that those exercises were very difficult, which made him wonder about himself, could it be that his level was still far behind?

So make up your mind to read the exercises in that workbook.

When she went home, Yang Kaiwen was not there, she has been in the library recently, leaving early and returning late, which also made Bai Zhou understand the hardships of the graduate school entrance examination.

After cutting some fruit for himself, Bai Zhou plunged into the study and opened the exercise book.

Twenty in total!

Bai Zhou took a deep breath and began to focus on the first question!

At two o'clock in the middle of the night, Yang Kaiwen got up and came out in a daze to pour water for herself.

When I turned around, there was still light seeping out from under the crack in the study door.

"Sure enough, none of the people who can succeed take shortcuts!"

Yang Kaiwen clenched her fists: "Work hard, struggle!" ”

……

"Well, it's very interesting, the small program I gave you yesterday only has five bugs, and someone changed a number, and fifty bugs broke out directly!"

Luo Sanyang stood on the podium, looking at the whiteboard with a smile, there were several typical examples on it.

Press the enter key and remain motionless.

He said, glancing at the back of the classroom.

Didn't see the white boat.

Didn't you come today?

Or is it because the exercises given to you scared people out of interest in computers?

Not really.

"You people, let alone meeting the needs of customers, whether you can be surrounded by bugs is already very good!"

As he was talking, Luo Sanyang saw a sneaky figure enter the classroom with his head down, and then found a place to sit down.

Bai Zhou couldn't stop gasping, and as soon as he raised his head, he just met Luo Sanyang's gaze, and Bai Zhou hurriedly lowered his head.

Overslept.

Those exercises were really too difficult, especially the last optimization, he tossed for more than three hours before he completely changed the bugs inside, and then fell asleep directly on the table.

When I wake up and see the time, it's 1:50 p.m.!

was so frightened that Bai Zhou was full of excitement, and he didn't have time to brush his teeth and wash his face, so he ran away.

Along the way, I don't know how many students were stunned.

Rao is like this, the class has been going on for nearly forty minutes, after all, there is a traffic jam on the road.

Bai Zhou calmed down his emotions again and again, and after a while, began to take notes carefully.

"Okay, Jing Hao, come to the office and find me in a moment!"

After class, the students rushed out, Bai Zhou took the notes, and saw that Teacher Luo also went out, so he hurriedly chased after him.

Luo Sanming didn't leave, when he saw Bai Zhou coming out, he waved at him, and when Bai Zhou ran to him, just as he was about to speak, Bai Zhou said: "Teacher, I've finished the exercises!" ”

Luo Sanming was still a little embarrassed about the wrong exercises he gave yesterday, after all, as a teacher of the Department of Computational Formulas, he would be so careless, you know, the programmer itself should be locked with the word rigor.

And as he expected, Bai Zhou should have run over, and then he was a little embarrassed and said that he wouldn't.

He waved his hand and said it was fine, but he had given the wrong exercise.

But......

What he never expected was that Bai Zhou would come to say this.

"What? What did you say? ”

Luo Sanming felt that he had heard it wrong, and asked again in disbelief: "Are you done?" ”

Bai Zhou nodded heavily and scratched his head: "I tossed all night last night, and these twenty questions are a bit difficult, especially the last one, which has been tossed until today's daytime, so it's too late!" ”

Luo Sanming opened his mouth and said hurriedly: "You give me the exercise book I gave you last night!" ”

Bai Zhou looked dazed, not knowing what Luo Sanming's expression meant, but he still obediently handed the exercise book to Luo Sanming.

Luo Sanming opened the booklet and his eyes shrank.

That's right!

This is the AOS professional exercise, there are 20 questions, that is the most complex exercise selected by AOS every year, this is not a student's exercise, but a system analyst like him uses it to brush capital.

Even Luo Sanming himself has been stuck on the eighteenth question.

To put it bluntly, no one has yet solved all the 20 problems contained in this year's AOS book.

Even on the AOS website, it has only only cracked the nineteenth question, and everyone is racking their brains for the twentieth exercise.

Luo Sanming pushed the exercise book in front of Bai Zhou with his backhand and pointed to the first question: "Are you sure you are solving this problem?" ”

Bai Zhou nodded: "Yes!" ”

Luo Sanming said again: "You look carefully! ”

Bai Zhou opened his mouth, lowered his head and looked at it for a while, he almost didn't recognize the word, and nodded: "It's this!" ”

Luo Sanming spread his hands: "Bring it to me and take a look!" ”

Bai Zhou opened the bag and immediately took out his notebook.

Here, Luo Sanming couldn't wait to come over.
