Han Yingqiu pushed the door and entered, said! "Yang went to the teacher, this inter-school computer competition. Is there anyone in your class?"

As the well-known school hua of the computer department and an important cadre of the student union, Han Yingqiu and Yang Yang certainly knew each other.For the inter-school computer competition she mentioned, Yang Yang also agrees a little.

This event was jointly sponsored by Jingcheng University and Shuimu University. Almost all the prestigious and confident universities in Beijing will send students to participate in this event.Of course, this event stipulates that only freshmen, freshmen and sophomores are allowed to participate, regardless of major.

"The students in our class have only been enrolled for half a year, what good skills can they have?" Yang Yang wondered, "I think our class should not participate in this competition!"

"This is not good!" Han Yingqiu was also in a dilemma. After all, this matter is also related to the school's face. As the initiator, if Beijing University does not send out half a freshman from each computer major to participate in the competition, it will be a shame. I'm afraid it's not easy.

Yang Yang naturally knew what Han Yingqiu was embarrassing, but on her side, she said, "It's hard to cook without rice, ah! You can't just get someone to report it. If you make a fool of yourself in the official competition, I'm afraid the school leaders will be even more embarrassed." have to die.

That's why it's better to hide one's clumsiness than showing ugliness." Yang Yang still didn't let go, saying: "Our class really can't find a candidate!" Speaking of this, she inadvertently glanced at the stack of make-up exam report cards.

Han Yingqiu looked bitter, and was about to leave, but Yang Yang's eyes lit up, and said: "Student Han, I have plenty of candidates here, but I don't know if he can do it, and will he participate?"

"Wing"

"His name is Jin Yuxing!" Yang Yang said.

Hitting Yu's forehead, Han Yingqiu exclaimed: "God, it's Hua! I forgot, if he competes, he will probably win!"

Seeing Han Yingqiu's surprised and delighted expression, Yang Yang wondered, "Why, you know him, so you're so sure of his level?"

Han Yingqiu said: "I haven't personally seen what his level is, so I can't guarantee it, but I have an intuition that he should be able to do it.

Yang Yang got excited now, and said: "Oh!? Since you are somewhat sure about Jin Yuxing, student Han, I would like to ask you, if a [-]-digit password is set on an e"d form, like your How long does it take such a big master to crack it? "

Han Yingqiu frowned and said, "Mr. Yang, why would you ask such a question?" After all, cracking codes is a disgraceful thing most of the time, and it's only natural for her to ask this question.

"I don't mean anything else, it's just just now." Yang Yang immediately told Han Yingqiu what happened just now.

After listening, Han Yingqiu immediately went to Yang Yang's computer, picked up the mouse and clicked on the system to check.

After the inspection, Han Yingqiu pointed to the stack of report cards and asked, "Mr. Yang, how long did you say it took Jin Yuxing to get this done?"

"About 5 minutes, I don't know exactly how long!" Yang Yang said.

Han Yingqiu was speechless for a moment, because by checking the printing log, she found that the working time of the latest printing task was five minutes and five seconds. Doesn't that mean that Jin Yuxing went from cracking the password to sorting to pressing the "Print, It took less than a minute? She felt incredible at such a fast speed.

"Mr. Yang, did you misread the time, or the form didn't have a password at all, or the field (1) in the form was already arranged according to each student's name?" Han Yingqiu asked.

"Impossible!" Yang Yang denied, "If you don't believe me, click on the form and try it yourself. I didn't lie. There is definitely a password and the header fields are divided by subjects."

Han Yingqiu didn't believe in evil, so she clicked on the excel sheet, and found that after it popped up, there was a prompt asking for a password.

Looking at Yang Yang, she immediately said, "The password is qxodfsaufjol123!"

Han Yingqiu quickly and honestly lost, and the excel table immediately popped up the content, and she immediately found that, as Yang Yang said, the header fields were mainly subjects, while the student names were all arranged out of order.

After clicking on the dozens of excel sheets that Yuxing left on the desktop, Han Yingqiu suddenly found out that

These tables are completely generated according to the names of the people, and then the subjects and results of the make-up exams under each name.

After confirming this, Han Yingqiu was completely shocked.Because it takes at least three or four minutes to make a single form like this at her speed, but looking at the generation time of these dozens of forms, it is actually at the same time. "A computer expert is far from Jin Yuxing's enemy.

"A fast person is not necessarily a master, but a master must be fast." This is an iron law in the computer world.Therefore, regardless of whether a password has been set for the watch before, the person who can have such a speed will never be a computer mediocrity.

Suddenly, Han Yingqiu recalled that experience in the library again, and in his heart, he became more and more sure that Jin Yuxing was a computer expert.

"How, are you sure?" Yang Yang said, "Can this Jin Yuxing compete?"

A gleam of determination flashed across Han Yingqiu's pretty face, and she said, "Absolutely! But I know he is quite stubborn, and it may not be easy for him to compete, so, Teacher Yang, you need to do more for him It's my job!" After she finished speaking, she added Jin Yuxing's name on the registration form in front of Yang Yang.

Before Yang Yang could say anything else, Han Yingqiu said hello and left.After all, there are many majors in the Department of Computer Science, so she has to visit them one by one!

Yang Yang didn't know that Han Yingqiu had left her the hot potato, so he sat on his seat and said to himself, "Since Jin Yuxing has this talent, then I will invite youhuo him to participate in the competition because of the absence of the school committee!"

As soon as Yuxing walked to the door of 105, he heard a loud commotion inside. He rushed over to see that the bespectacled man who taught cheating at the end of last semester had come again and was playing mahjong with Zhang Yi, Cao Donglin and Xiao Nie. !

Seeing Yuxing coming in, the 105 people got up to greet each other.But the four of them were just right, and Yu Xing didn't need to get a slot as soon as he came, so he moved a plastic stool and sat next to the mahjong table.

The guy with the glasses stood on the living balcony and said loudly: "Listen up, I'm starting to talk, if you don't laugh anymore, I will admit it!"

Yu Xing looked confused, pointed to the mahjong on the table and asked, "Isn't he playing mahjong? What kind of crazy is he, and what is he going to talk about?"

Zhang Yi curled his lips and said, "He's so stupid that I made me make up the exam. Let's see if I don't play him to death today."

Cao Donglin nodded in agreement and said, "That's right, if I don't let him lose a week's meal today, I will never give up!"

The more Yu Xing heard, the more confused he became, and he hurriedly looked at Xiao Nie. After all, he and Brother Glasses are the only ones who have no hatred among the three.

"Third brother, we don't pay for playing mahjong. We lose the meal. As for the quality of the meal, it doesn't matter if there are vegetables or meat. Whoever lights up the cannon will lose a meal. Self-mo wins three meals at a time. Keep counting." Xiao Nie explained, "This old guy has been on the bar several times in a row, and he lost so badly!"

Yu Xing wondered: "Since it's a loser, what is he doing?"

"He lost too badly, and wanted to save some food money, so he came up with another bad idea." Cao Donglin said disdainfully, "Every time the loser can stand on the balcony and tell jokes loudly, and he can tell a few jokes as soon as he loses a few meals." One, as long as one person who wins a joke is laughed at, then the owed can be written off. "

"Cut! It's a good idea. I'm holding back my laughter today. Anyway, the free jokes are just a joke..." Zhang Yi said harshly, "If I don't win TND's meal for a month, I'm sorry for the supplementary exam fees!"

It seems that these two guys are holding back to make their glasses bleed profusely.

However, Yu Xing is not too lazy to care about the grievances between the eldest brother and the glasses brother, but he is interested in waiting for the glasses' jokes.

At this time, the glasses began to talk: "An old lady called the police: "Mr. Police, there is a naked man in the building opposite my house! "

To be honest, the beginning of this joke aroused the passions of Zhang Boss and Cao Lao Er, and both of them pricked up their ears, waiting for the next one.

"[Police] said: "Ma'am, don't be afraid, we'll be right there" A few minutes later, [Police] arrived at the scene... [Police] asked: "Madam, where is that indecent man? , the old lady said: "It's just upstairs opposite..."

Speaking of this, Brother Glasses deliberately stopped talking to see everyone's reaction.After all, this was his last joke, and it was related to eight meals.In the first month of the new semester, he basically lost all the meals in the first half of the month. Whether he ate dry or drank in the second half of the month was all based on this joke, so he couldn't help being careless.

However, the biggest fear of this joke is hesitation.Originally, Zhang Yi and Cao Donglin still had half-joyed faces on their faces, but after the glasses stopped, they turned into poker faces again.

Seeing such a situation, the glasses brother was full of distress, but in desperation, he could only continue: "...〖Police〗The policeman stretched out his head to look around, and asked suspiciously, "Where the hell is it?Why didn't I see it?" The old lady said: "You can see it with a telescope",

Hearing this, Yu Xing was startled, and suddenly burst out laughing.

Cao Donglin then laughed.

"Hahahaha" Xiao Ne also burst out laughing.

Dudu suffocated Boss Zhang, who was hit by glasses, his face flushed, but he just didn't smile.

Glasses cried and said: "Brother, you should just laugh and leave!"

Zhang Yi didn't answer him, but was still struggling.

Yu Xing patted him with a smile, and said, "Boss, it's not good to hold back when you laugh!"

"Wow, haha, shit, I almost managed to hold it back!" Zhang Yi laughed and complained, "Third brother, it's all your fault, I lost eight meals in one fell swoop!"

Seeing Zhang Yi smiling, the glasses finally breathed a sigh of relief, and said, "Oh yeah! I've saved my lower body!"

105 people laughed again.

After laughing, Zhang Yi asked maliciously, "Are you still coming?"

"No more!" The head of the glasses shook like a splashing drum. "Your father is really good at playing mahjong. I'm no match, so what a fart!"

Boss Zhang refused to obey, and shouted: "No, it's still early for dinner, at least two more laps!"

"If you don't come, you won't come!" Glasses said shamelessly, "Anyway, I don't have to worry about my debts. If you dare to threaten me, be careful that we won't even feed you the meals before!"

Before Zhang Yi could say anything, Cao Donglin and Xiao Nie stood up together and said, "How dare you!"
