Hu Xuefeng didn't know that he was careless, which made the math teacher Xue Feng lose face, and accidentally made Mr. Xue worry about himself.

At this time, Hu Xuefeng was looking at Yang Yagang speechlessly with a depressed face, because Yang Yagang came to the classroom and first came to him to ask for the process of solving the problem.

Hu Xuefeng pouted his lips very embarrassed, "Teacher Yang, don't be embarrassed for me, I only know the answer to this question, the process of solving the problem, I don't know." ”

Hu Xuefeng originally just wanted to pretend to be low-key and bluff the math teacher Xue Feng, but he didn't expect to be seen through by Yang Yagang so quickly, and he was a paper tiger.

Hu Xuefeng was deeply embarrassed.

"No...... Ahem...... Won't it be right......" Yang Yagang's characteristic tone made the students in front of him more and more embarrassed, but Yang Yagang did not continue to delve into it, so he returned to the podium to give a lecture, as for the words he said to Xue Feng before, he seemed to have forgotten it, but he didn't mention it.

Hu Xuefeng felt that he was a little despised.

Not only is he young and crazy, but he is still uneasy, Hu Xuefeng suddenly wanted to write out the process of solving this question, although he didn't have to do it.

With the stubbornness that only a few young people can have, Hu Xuefeng took out the acting herbs, buried his head and began to reason and calculate, he wanted to solve this problem.

Hu Xuefeng first used the method of reverse deduction to solve the problem, because he knew that the answer was that the Germans raised fish, so he thought that if he could reverse the deduction, it would be a way to solve the problem.

The answer is known, and the process is reversed.

For the Chinese in later generations, this is a very common thing, you don't see, up to ballistic missiles, aircraft carriers and other national heavy weapons, down to mobile phones and computers and other conventional technology products, which development, without the help of backward thinking?

It is no wonder that Western countries such as the United States often say that China is a big copycat country, but it is really because the Chinese people's backward thinking is too strong, and in Hu Xuefeng's view, reverse deduction is also an innovation.

If, like neighboring Ah San, no matter how much advanced equipment he buys, he has not seen any advanced weapons come out, it cannot but be said that Ah San lacks this unique thinking of reversing and then innovating.

A quarter of an hour later, Hu Xuefeng used the method of reverse deduction to get the first complete solution process, but Hu Xuefeng was not satisfied.

Immediately afterwards, Hu Xuefeng sorted out his thoughts and began to think about the second way of solving the problem.

This time, Hu Xuefeng plans to use the Sudoku method to solve the problem.

Compared with backwards, Sudoku's thinking is undoubtedly more challenging and difficult, and what Hu Xuefeng wants is this feeling of facing difficulties and riding the wind and waves.

Hu Xuefeng listed the conditions he knew one by one according to the 15 hints he knew, and made a table according to nationality, house color, animals, drinks and cigarettes.

First, he determined the identity of the British, then began to deduce the Danes, Swedes, and Norwegians, and finally, the identity of the Germans was naturally revealed.

Rao is Hu Xuefeng's head is smart, but after such reasoning, he still feels tired.

However, there is finally an explanation.

The bell rang after class, and when Yang Ya was about to leave, Hu Xuefeng presented his acting herb to him, "Teacher Yang, this is the process of solving the problem." ”

Yang Yagang looked at the handwriting on the papyrus, and first saw Hu Xuefeng reverse to solve the problem, he was already very surprised, but when he saw that Hu Xuefeng actually used the Sudoku method to solve it, he could no longer be calm, Yang Yagang looked deeply at the student in front of him, and asked in disbelief, "Is this really what you did?"

Hu Xuefeng nodded a little arrogantly, then turned around and returned to his seat, leaving only Yang Yagang with an unpredictable back.

"Is this really a junior high school student?"

Yang Yagang knew the difficulty of the question, he asked himself, he could do the most to solve the problem backwards, he also thought that Hu Xuefeng would not, and when he returned to the office, he would write out the problem solving process by himself, and then block the mouths of Xue Feng and others, but now it seems that there is no need for this at all, because Hu Xuefeng is better than him.

As soon as Yang Ya returned to the office, he happened to be the substitute teachers of the third grade of junior high school, he smiled, and then walked straight to Xue Feng's desk, "Teacher Xue...... Ahem...... This is Hu Xuefeng...... Ahem...... Give your solution process ......"

Xue Feng was stunned!

Can it really be solved?

Xue Feng was still a little unconvinced at first, you must know that Yang Yagang left, and he and Gao Bowen and several people deduced according to the answer given by Yang Yagang, but they have not yet been able to launch the whole process.

Xue Feng took the herb and glanced at it, and the whole person was shocked.

"This ...... This ......"

Xue Feng carefully watched the two problem-solving steps in the textbook, and his first reaction was the same as Yang Yagang's before, he was wondering if this was written by Hu Xuefeng.

Yang Yagang, who was standing in front of him, seemed to see his thoughts, Yang Yagang nodded, and said with emotion, "Teacher Xue doesn't have to doubt that this is exactly what Hu Xuefeng did." ”

Yang Yagang's words were like a hammer of a thousand jun, and Xue Feng's head was dizzy and dizzy, and at this moment, he deeply remembered the three words Hu Xuefeng.

Hugh said that Xue Feng, even Gao Bowen and several other math teachers, were all ashamed.

In an instant, Hu Xuefeng's name began to spread in the office of the third junior high school teacher, and when school was out in the afternoon, all the teachers in the entire Yangcheng No. 8 Middle School knew that there was such a little monster in the third and fifth classes of the junior high school.

As a result, Hu Xuefeng became the focus of all teachers, which made Xiao Hu feel that Yali Mountain was big.

"Did I say you offended the teacher?"

At the end of school, Li Dong said without complaint while sorting out his schoolbag, "All afternoon, the English teacher, chemistry teacher, and geography teacher all called your name, and you also memorized this point, right?"

Hu Xuefeng shrugged helplessly, "This shows that the teacher attaches importance to me and wants to focus on cultivating me, but you, you haven't slept all afternoon, haha, speechless!"

Li Dong suddenly cried with a sad face, "You kid still knows, you know, the teacher looked this way all afternoon, so that I yawned and didn't dare to hit one, do you know how much damage this is to a fat man? No, you have to compensate me, you have to invite me to drink a bottle of Coke." ”

Hu Xuefeng is now rich in his pocket, he nodded, then turned to Lin Lan and said, "Let's go, I'll send you home." ”

Behind "I lean on the ......", classmate Li Dong suffered a critical hit of 100,000 points in an instant!

Lin Lan panicked, Hu Xuefeng's words, the surrounding classmates heard it, she didn't look up, she could know that the classmates must be gossiping about her relationship with Hu Xuefeng, Lin Lan had no experience at all, and didn't know how to answer, but Hu Xuefeng didn't give her time to think about it, and helped Lin Lan pack her schoolbag, and Hu Xuefeng pulled her away.

Along the way, Hu Xuefeng naturally kept sprinkling dog food, which also caused Li Dong, who had a budding spring heart, to suffer all the way.

It wasn't until the three of them were about to get off the bus that Li Dong suddenly remembered that Lu Weimin asked Hu Xuefeng to go to the grove, "Crazy, have we forgotten Lu Weimin's house?"

After hearing this, Hu Xuefeng blurted out almost without thinking, "Who pays attention to him, he has to wait, let him wait, after all, I am also very busy, and I still have a lot of homework today." ”

Burst......

Li Dong was shocked, and at the same time silently felt sorry for Lu Weimin's classmate for a second, who made Lu Weimin regard Hu Xuefeng as a rival in love, but Hu Xuefeng didn't love Lu Weimin at all?

Yes, in Hu Xuefeng's eyes, Lu Weimin really didn't want to go home to do his homework.
