Han Sheng from the Department of Electronics.

Vice President of the TMS Association of Electronics Department and Deputy Captain of the Waist Drum Team of Jianghai University.

His academic performance was ranked first in the college for three years.

Cao Rong was just now amazed at Cao Zhi's full scores in six professional courses, but the guy's grades became even more terrifying as soon as he started. He had 15 full scores, with three subjects remaining, one 99 points and two 98 points. What does it mean? This guy was deducted a total of 5 points in all courses.

You should know that among the top academic masters of Jianghai University, everyone is comparing how many points were deducted in total in three years of college. It is said that the scores deducted in all courses are less than ten, and that is a true God-level master. Cao Zhi just now was not good. Although he scored six full points, the scores deducted in total are still a few tens. After all, there are not many twenty courses in total in three years, and the scores deducted are single-digit. What is this concept? Maybe this guy, the god of exams.

"Your grades are very strong, but your..." Before Shi Sen finished speaking, Han Sheng interrupted domineeringly and said, "Sorry, you are not qualified to interview me. Please ask that stingy guy."

Shi Sen was angry.

Liu Chen said bluntly: "The undergraduate courses are very complicated. Just now, Cao Zhi got full marks in six major courses, which shows that he loves his major very much and has studied very deeply. The exam is too simple for him, but you actually got full marks in fifteen. Even every science and engineering student has to study. However, your professional achievements are not outstanding, and the honors you have won are all extracurricular amateurs. In my opinion, there is no technical content at all. So can I come to a conclusion that you just love exams and are addicted to full marks?"

This question is sharp. The students waiting outside were shocked by Han Sheng's extraordinary results. No one would pay attention to other things. Five points were deducted in eighteen courses. This is probably the first person in the Jianghai University exam. It is difficult to surpass it. You should know that the difficulty of the Jianghai University exam is much more difficult than that of ordinary pheasant universities or even ordinary 211 universities.

In some ordinary universities, teachers usually hold a book to read from beginning to end, and they can mark the scope before the exam. Even so, so many students fail the subject, and the quality can be imagined.

It is no wonder that with the expansion of enrollment in China, the number of college students suddenly increased, and college students who were unemployed after graduation were everywhere. The reason is that they blindly pursue bachelor's degree. Just like these ordinary universities, what can graduates do? It can be said that they don't understand nonsense, so it's better to find a technician, at least they can work by getting started.

If a poor family in the countryside is admitted to an ordinary university, the parents have great expectations, but they don’t know how to use it. The tuition fees spent all their hard savings in the past few years. After graduation, they might have to rely on their parents. They barely find a job in the city and barely support themselves. It is even more out of reach for buying a house and marrying a wife. Compared with friends in the same countryside, they drop out of school early to work and get married early. The wife and children have a warm kang, the house is at home, the bank card has a deposit, and the car is bought, and life is also enjoyable.

When asked by Liu Chen's question, Han Sheng was suddenly at a loss. He achieved such results. He was undoubtedly very proud in the eyes of his parents. When relatives and friends knew that they would praise him as a role model for their children to learn from. In the eyes of his classmates, he was a proud god of learning. In the eyes of countless poor students, he did not have the qualification to kneel and lick.

But at this moment, he was a little confused. He thought for a while and answered honestly: "I have understood a truth since I was a child. I will get praise from my parents, teachers, and respect and envy from my classmates by 100 points in the exam. Therefore, I have obtained countless full scores from childhood to adulthood. After I arrived at university, this kind of test habits still affect me. Whenever I take the exam, I will want full scores. You are right. I don't love majors very much. I just spent a lot of effort to learn to get full scores. But I didn't get full scores in those three exams, and I was sad for a long time."

Han Sheng was a little lonely in his words. When I was proud of the achievements I had achieved, I realized how ridiculous and naive it was to spend so much time to get the full mark. I also wanted to change it, but this inertia was too strong. Whenever I encountered an exam, I still did this unconsciously.

Liu Chen also sighed. This is a typical good student in China. The whole society praises such students, but what is the use of such students? Learning the known and simple knowledge thoroughly can only be said to be a waste of intelligence.

"You don't meet our requirements."

"As long as you say your requirements, I will definitely achieve it." Han Sheng had a stubborn personality.

I was not interested in students who got full marks inertial disease like Han Sheng, and pondered for a moment: "To be honest, I don't actually like students like you. Since you persist so much, I will give you a chance. In fact, the most important thing in scientific research is thinking ability like a mental illness. I will give you a few questions below to test your thinking ability. Each question is five minutes. If you can satisfy me, if you can't answer one of them, I can only apologize."

Han Sheng nodded firmly.

Liu Chen smiled and said, "Okay, then the first question will begin."

“How many times does the hour and minute hands overlap in the day?”

Han Sheng’s first intuition after hearing the question was 24 times, but he immediately thought that it would not be so simple, so he hurriedly started to think about it.

When the minute hand and the hour hand start to move from 12:00, the minute hand of the clock moves in t circles for t hours, and the hour hand is t/12 circles. When the two watch hands overlap for the first time, the minute hand is one circle ahead of the hour hand, that is, t=t/12+1, and t=12/11, that is, the first time the watch hands overlap at 12/11.

Change the number of overlaps to n, and then change the t in the formula to 24, and you can get: 24=2+n. Obviously, n=22, that is, two watch needles overlap 22 times in a day. They never overlap at 11 o'clock in the morning or afternoon, because they have to reach the 12 o'clock direction of the dial at the same time.

In just three minutes, Han Sheng gave the answer, 22 times.

Liu Chen nodded and said, "Yes, I got the answer in such a short time. This question is actually very simple. The difficulty lies in how to express specific problems in mathematical equations. This is a kind of thinking expression ability, which is extremely important in high-level scientific research. So listen to the next question."

"The problem of crossing the bridge is that the four people need to spend a shaking suspension bridge at night. Unfortunately, they only have one torch, and the bridge is too dangerous, and they cannot pass through this dangerous bridge without the help of the torch. What's more unfortunate is that the bridge is not very strong, allowing at most two people to cross the bridge at the same time. The speed of the four people cross the bridge is different, namely: 1 minute, 2 minutes, 7 minutes, and 10 minutes. Obviously, the time it takes for two people to travel to the bridge at the same time depends on the slowest person. So, what is the shortest time it takes for them to all of them to spend this bridge?"

Han Sheng’s first idea was to use the fastest person to repeatedly cross the bridge to pick up and drop off others. The time required is 2+1+7+1+10=21 minutes. The answer was obtained in just a few seconds. Han Sheng immediately realized that this question may not be so simple. The shortest time must be less than 21 minutes, and there must be a faster way.

How should I cross the bridge? Han Sheng was so anxious that his forehead was full of sweat. The two people who used the longest time must cross the bridge together to save time. However, if these two people passed together, then it would take too long for one of them to send the torch to the opposite side. What should I do? Han Sheng was very nervous, and his thinking had to jump and diverge at this time. How to solve this problem? Can you leave a person with fast tutorials on the other side in advance? Han Sheng was happy and finally got the answer.

"The shortest time should be 17 minutes."

"Oh, tell me what you think about solving the problem."

"First let 1 and 2 cross the bridge together. It takes 2 minutes. Let 1 come back with the torch. It takes 1 minute. Let 7 and 10 cross the bridge together. It takes 10 minutes. Let 2 come back with the torch. It takes 2 minutes. Finally, let 1 and 2 cross the bridge together. It takes 2 minutes. The final total time is 2+1+10+2+2=17 minutes."

"The thinking ability is really good." Liu Chenhao praised Han Sheng without hesitation, and then said: "What can be seen from this question? Resources should be optimized and coordinated. People who have the longest 10 minutes of bridge time must cooperate with seven minutes to maximize the use of the ten minutes required for the bridge. It takes 1 minute and 2 minutes. It is a good university talent and needs to be reused. What I want to tell you is what you are good at is to maximize the use."

Han Sheng nodded thoughtfully. Only then did he realize that when Liu Chen gave him a question, he was also guiding his thinking direction, which had subtly changed his full-score inertia disease.

"The third question is: Does your husband have an ex-encounter encounter? There are 100 couples in a small town, and they all abide by a strange custom: if a wife finds that her husband has betrayed her, she will kill her husband that night. Women in the town know the secrets of other people's husbands, but they will not tell them. In other words, every woman only knows the situation of other men except her husband. Suddenly one day the mayor announced that at least one man betrayed his wife. Assuming that the mayor said the truth and everyone believes what the mayor said, what will happen next?"

Han Sheng felt confused when he heard this topic and could not grasp the key points of the topic at all. In a hurry, he could only use the exhaustive method.

Let's first assume that only one man betrayed his wife. At this time, the man's wife will suddenly find that she doesn't know any news about a man having an affair. The other 99 women know that one man betrayed his wife, that is, the truth. The only explanation for this is that there is and only one man who has an affair is his husband. So she will kill her husband that night.

What if there were two men? At this time, 98 women in the town knew the truth, but the other two women only knew that one man had an affair, and they were not sure whether their husbands also had an affair. So on the day the mayor announced the incident, the whole town was in peace. But on the second day, when the two women found that the other party had not executed their husbands, they would realize that more than one man had an affair. That was that two men had an affair. In this case, one of them must be his husband. So, these two women would execute their husbands at night at the same time.

Han Sheng made a brain teaser, and so on, can it be summarized that if there were n unfaithful husbands in the town, they would be executed on the n night after the mayor's announcement?

When the time came, Han Sheng said his analysis without confidence. Liu Chen began to appreciate this student a little. Although he had exam habits and his thinking talent was amazing, he deliberately cultivated him. He smiled and said, "Thinking ability is indeed unique. If you didn't spend too much time pursuing full marks in the exam, I believe you have achieved extraordinary results. What I want to tell you about this question is: Sometimes although there is only a very small amount of information, as long as you analyze it carefully, you can still draw effective conclusions."

Of course, Han Sheng was unwilling to admit defeat. Judging from the three questions just now, Han Sheng felt that he had gained a lot, and his thinking ability was suddenly squeezed out, so he nodded firmly.

"Thank you, if it's possible, I want to meet you, you're amazing."

"There will be a chance in the future, and you will pass."

Han Sheng breathed a sigh of relief and realized that his spine and forehead were covered with sweat.

As soon as he walked out, Sister Dou Dou greeted her and asked anxiously: "Classmate, you are very awesome. You have solved such difficult questions on the spot. Have you seen them before? You have known the answer for a long time?"

Han Sheng looked at the elder sister with a cold expression and said arrogantly: "This is the first time I have heard it. No matter what difficulties I encounter, I will devote myself to it."

"But it's impossible to think of it in such a short time?"

"That's you, not me."

It was obvious that Dou Dou didn't give up and asked, "Do you have any tricks?"

Han Sheng pointed to his brain, not wanting to bother her anymore.

In the room, Fang Zhigao smiled and said, "This guy is too powerful. If you focus on scientific research, it will be too terrifying."

Liu Chen shook his head and said, "If he is given a specific research direction and specific problems, I believe he will definitely be able to solve them, but he does not have the ability to discover problems by himself. Haha, it is definitely a talented person to use them in the right place."

Shi Sen said sincerely: "Mr. Liu, you are so powerful. You are so powerful on BBS. I see these strong men are all coming towards you. We are sitting here with the ears of deaf people. Master Fang, let's go back to the laboratory."

Fang Zhigao also nodded.

When Liu Chen saw that the interview had entered the second half, he nodded and went back to the chair, and smiled and said, "Why aren't there a few female academic masters here? Girls from Jiangda are generally better than boys."

Cao Rong smiled and said, "That was scared by you."

"Is it that scary?"
