395 Yin and Yang made a mistake!

Although the test papers are all about computer-related topics, there is one thing that makes Yuxing feel very strange, that is, there is no name written throughout the paper. ~~ Fortunately, the upper left corner of the paper reads the words "Affiliation Number" followed by a blank underscore, which is obviously a place to fill in the number.

Seeing this, Yu Xing slandered in his heart: "It should be the admission ticket number? Return it to the school! How dare you take out the paper with such obvious mistakes!"

Of course, Yu Xing didn't have doubts in his heart, but he came late and sneaked into the classroom, so he didn't dare to ask the invigilator.So he could only follow his own understanding and underline the six-digit number on his admission ticket number.

Next, according to his usual habit, Yu Xing scanned both the front and back of the test paper, and then frowned.

"Is this question too difficult?" Yu Xing thought.Indeed, the questions on the test paper are all major problems in various aspects of computers, including software, hardware, and a combination of software and hardware. Each question involves a wide range of knowledge, even those real computer experts may not be able to understand all of them. Know.

Take the penultimate question on the back as an example, how to reduce the heat loss of the motherboard's north and south bridge chipsets without compromising their efficiency?This is one of the big problems with computer hardware.The hardware knowledge involved in this question is almost all-encompassing.

This shouldn't be a contest problem at all, because most of the motherboard manufacturers in the world have not completely solved this problem.If a college student can come up with a feasible solution, he is definitely a national treasure.

As far as Yuxing knows, most of the solutions are to control the current through the chipset within a certain range. In this way, the heat dissipation will naturally be low if the current is small, but the current is small, and the electrical signal is also reduced. The temperature of the chip has dropped, but its work efficiency in processing electrical signals has also dropped, and the cpu receives fewer work requests, the cpu usage rate is not high, and it is idle most of the time. Yes, taxis have a Formula [-] engine, but they don't work a tenth of the way.

With such a topic, and each question is about the same level of difficulty, it is not surprising that Yuxing complained.Even if someone can answer such a difficult question, it is definitely not something that can be answered in just two or three hours of the exam.

But... Yuxing rolled his eyes and remembered the Apple laptop that Yuqin modified for him. It seemed that that thing had solved this problem!As for how to solve it, Yuxing is not very clear.

"Hey buddy, what are you thinking?"

In Yuxing's ear, the voice of the bearded old man sounded again.

After waking up, my dear boy, I don’t know when Hu Zha had already sat on the seat behind Yu Xing and was looking at him with a big smile on his face.

Yu Xing, who had just finished reading the paper, was worrying about how to solve the problem. Hearing what Mr. Hu Chan said, he asked impatiently, "Is there something wrong?"

Intimidated by Yu Xing's aura, Hu Chan was a little apprehensive, his smile was a little stiff and he said: "It's okay, it's just that you are not doing well in solving the problem, so I want to come over and discuss with you."

scare!

Yu Xing's heart skipped a beat, and he slandered: "This is a fucking exam with discussions? And you are so frankly speaking... It's not shameful to be caught cheating in your own school, but if you get caught here, then But the embarrassment is thrown outside the school."

Feeling uneasy, the bearded guy behind said to Yu Xing again: "My roommates have escaped by shit today, and there is no one around to discuss it, so I have to ask you to get together... Yes Alright, my name is Zhang Yue, from HKUST, what's your name?"

Yu Xing felt contemptuous in his heart, and thought, "It's fine if you say that you are mature, anyway, there are not a few mature-looking people in college, but who are your roommates? Are you still running away from shit? Standing in a latrine and not taking a shit is abominable, it’s purely an empty latrine to prevent others from shitting.”

Little did he know that the roommate Zhang Yue was talking about was not the dormitory roommate Yu Xing thought of at all, but an apartment roommate.

But thinking about it, out of politeness, Yu Xing still introduced himself indifferently: "Jin Yu Xing, from Beijing University... I said, this exam will involve a group discussion?"

Zhang Yue rolled his eyes and said, "What's wrong with this kind of test? Anyway, we will focus on the discussion at that time."

Yu Xing also thought about it. In the previous preliminaries and semi-finals, in fact, the Beijing University Computer Association had public explanations on the test papers after the games, but he had never listened to them.Just thinking about this, Yuxing took a closer look at the candidates in the front row, and found that there were indeed many people who exchanged a few words from time to time, and some even used things like netbooks and mobile phones.

The invigilator on the stage below knew the situation at a glance, but turned a blind eye and did not interfere too much.

Although Yu Xing was suspicious, he was relieved when he thought about the difficulty of the question.

There are many problems that have never been encountered in books. Even if they are discussed or searched online, they may not be able to get the desired results.

"How is it? Brother, have you gone through all these questions?" Zhang Yue asked, "Which question do you have an idea for? Tell me and I will help you refer to it."

Yu Xing shook his head and said, "Not yet. What about you?"

"I don't have either." Zhang Yue sighed, "I think I'd better go to the technology forum to search, maybe I can find something." As he said, he grabbed his bag and took out a laptop without a battery from it. The computer, by the way, took out a small plug-in cable board, handed it to Yu Xing and said, "Brother, there is a plug socket under your feet, check it out for me!"

Yu Xing hesitated for a while, then took the seat, and said: "It just so happens that my phone is out of battery, let's charge it by the way." After speaking, he took out the charger from his arms, connected it to the phone, and connected it to the phone. on the cha line board.

Zhang Yue didn't take it seriously, opened his notebook, and turned his attention to the Internet.

Yuxing pinned the Bluetooth to his ear, connected Yuqin's phone, and asked the third-to-last question.

Yuqin explained for nearly half an hour in terms that are easy for Yuxing to understand, before explaining the general solution to this problem, and there are many other technologies involved in this framework solution, Yuqin has one by one Made a brief explanation.

In the end, Yuqin concluded: "Boss, with today's earth technology, this plan can be put into practical use, but many branch technologies are derived by me by simplifying higher-end technologies, and have not been proved by feasibility, and I haven't told you the details of these technologies in too much detail, do you want me to talk about them in detail?"

Yu Xingtou said: "It's not necessary..." But by the way, he asked a few more questions on the test paper, and Yuqin also briefly gave a framework solution.

After Yuqin explained everything in detail, more than 80 minutes had passed.

Yu Xing was speechless, and sorted out the solutions to the problems that Yuqin just mentioned in his mind, and was about to pick the key points in the solution and write a few strokes on the test paper, but Zhang Yue patted his Shoulder, said: "Dude, help me pull out the wiring board! I'm going to commit suicide."

"Ah? Are you finished?" Yu Xing asked in surprise.

"It's far away. I wrote and copied a few sentences on the second question on the front, and the rest are whiteboards!" Zhang Yue pouted, "Brother, I think you have been stunned for a long time in front of you, and you haven't started writing, why don't you Copy some more and I'll hand it over?" As he spoke, he handed over his horribly empty paper.

Yu Xing took it over and took a look, and found that Zhang Yue's answers were all nonsense, even if it was copied, it didn't make much sense, but it was hard not to copy, so he chose two seemingly important words from the nonsense answers and copied them in his own. on the paper.

Zhang Yue looked at it and yelled strangely: "Brother, it seems that your level is higher than mine, please leave a call!"

"What's your number?" Yu Xing asked.

Zhang Yue hurriedly said his mobile phone number, and Yu Xing dialed it.

"It's clear!" Zhang Yue yelled in a low voice, "I'll hand in the papers first. Let's make an appointment for dinner when we have time."

Yu Xing nodded, watched him go, and then began to write the paper.

An hour later, there were eight major questions on the paper, and Yu Xing completed three of them, and the answers were exactly what Yuqin told him.Of course, not all.He did not explain the key points of some technologies in the solution, but only vaguely stated that compared with solving the original problem, the technology proposed now is better for tackling key problems and more practical.Such an ambiguous answer is also in line with the characteristics of the framework plan. It only determines the direction of research and research, and the details of a certain technology are not discussed.

By the time Yuxing handed in the paper, two-thirds of the people in the classroom had already left.Like everyone else, Yu Xing put the paper on the podium and walked out of the classroom without bothering the invigilator who was writing and drawing.

Not long after Yu Xing left the classroom, another guy came to the podium and twitched loudly.

The invigilator raised his head and glared at him. He picked up the paper that the man put on the podium and wanted to put it under the podium: "Huh!? Why is there an extra test paper here?"

"Maybe it was left by the one who left just now!" He answered casually, and this guy also left on his own.

The invigilator glanced at the extra paper, saw that the second question on the front was only two sentences, and couldn't help sighing: "Another ignorant guy, it seems that our country is almost dying of computer research. "

Looking at the "Affiliated School Number" in the upper left corner, the invigilator who knew the fate "slapped" the case and said angrily: "Who is this so messed up? If you don't fill in this place, I will treat it as your jiao The blank paper is ready, but you dare to fill it out, do you really take this as a joke?"

At this time, another one came to hand in the test paper. Seeing that the invigilator was angry, he hurriedly asked, "Academician Liang, what's wrong?"

The invigilator slapped the paper on the stage and said, "Look for yourself!"

The man glanced at the place where the invigilator pointed, and immediately laughed, and said, "It starts with 987? How can there be such a school number, this buddy is really talented."
