Chapter 81: Don't leave after school, fight three more questions!

This question is very similar to the question of the monkey dividing peaches, which was asked by the famous American physicist Professor Tsung-Dao Lee when he visited the University of Science and Technology of China and met with some students of the junior class when he came to China to give a lecture.

First of all, you need to determine how many walnuts are left after the last magic mouse throws the walnuts, which is the key to solving the problem!

Soon, formulas appeared in front of Wu Cheng.

This is the first time that Lin Qiu and Hengjue have seen Wu Cheng personally write this special formula.

Before, Heng Jue was very respectful of this kind of algorithm, and now he can see it with his own eyes, and he is as excited as an eighteen girl, and he can't wait to jump high on the spot!

Then, it was determined that there were 1,020 walnuts left.

Take a long breath of relief, know the number of walnuts at the end, and then forget it, you just need to go backwards step by step.

It didn't take a pillar of incense, Wu Cheng gave the final answer, a total of 3132 walnuts!

Hearing the correct answer, Lin Qiu's face turned pale.

The worst-case scenario he could think of would be that neither side would be able to calculate the other's problems and end in a 0-0 draw.

But Wu Cheng obviously didn't want to give him this opportunity, he wanted to win, and he had to win beautifully!

"I'm sorry, it's time for me to ask the question. ”

Wu Cheng himself is a bug, his problems can be said to be extremely negative, those questions are extremely computationally intensive, Lin Qiu is destined to not be able to solve them in the short term.

"The second question is relatively simple, plant 20 trees, 4 trees for 1 row, and ask how many rows can be planted at most. ”

At first glance, this question sounds very simple, as if a 5-year-old child can compare and compare.

Kong Haoda frowned slightly, Wu regret Isn't this an obvious release of water?

Don't be polite to Lin Qiu, who is mixed in the rivers and lakes, the most important thing is the word "ruthless"!

The opportunity is rare, how can you just let this old guy go.

After listening to Wu Cheng's question, Lin Qiu showed a relieved smile, and thought, "The young man is still more up-to-the-road, and he knows how to give the seniors a step!"

For the sake of being so sensible, if you have any requirements, I will try to meet you!"

Seeing the other party's relaxed look, Wu Cheng couldn't help but sneer in his heart, "I'm still in the mood to giggle here, I'll watch you cry today!"

This question has plagued the world for more than 300 years! There is still no final answer, and the most people have only placed 23 rows, so I'll see how you put it today!"

Lin Qiu casually posed a 4*5 phalanx, roughly counting 5 rows!

Just as Lin Qiu was about to say his answer, Heng Jiushan couldn't help but fiddle with the phalanx, posing 4*4, 4 trees alone, "Isn't this 11 lines?"

Suddenly, Lin Qiu seemed to have been stepped on by his tail, staring at the phalanx in front of him.

It seemed that he remembered a dangerous place he had explored, and the lock plate at the door was similar to it!

"It's okay, the three of you can count it together. Wu Cheng said generously.

The three of them did not refuse, because for people like them who have been obsessed with arithmetic all their lives.

Arithmetic is the whole of their lives, and it would be a pity if they couldn't do the math when they encountered such a good problem.

Especially after being told the answer, it will make them feel that they have lost the opportunity.

Hengjue also joined the formation of troops, and various formation methods emerged in an endless stream, and the number of lines also changed with the continuous change of the three-person formation, becoming more and more.

At this time, there was still half contempt in Kong Haoda's eyes.

Wu Cheng seems to be a very ordinary question, but it is difficult for the three people of the Nine Shadows and One Vein to be like this!

This junior brother is really a treasure boy!

Finally, the three of them seem to have exhausted all their strength and came up with the final answer, 18 lines!

When they pushed out this number, the three of them turned pale, especially Lin Qiu, who was even more tired as if he was several years old.

The final pattern is in the shape of a pentagram on the outermost side, an inverted pentagram on the inner layer, a pentagonal on the inner layer, and an inverted pentagonal on the innermost part.

Wu Cheng smacked his lips, the computing power of these people can be said to be not weak, but compared with the wisdom of the entire human race, it is still not enough.

Shaking his head, "To tell you the truth, the real answer is far more than 18 lines!"

This answer was expected by the three of them in their hearts, but when it came out of Wu Cheng's mouth, they were still shocked.

Sure enough, 18 lines are still not the limit of this phalanx.

"Do you want to know the final answer?"

Hearing this, the three of them waved their hands together, "Don't talk about it, it's not easy to encounter a good question, I admit defeat in this game, don't say the answer."

When I go back today, even if I don't sleep, I'll have to put this out!"

Heng Jiushan wiped the sweat on his face, and said in the same voice, "Indeed, the formation is ever-changing, I have a first glimpse of the way, there should be a play tonight!"

Lin Qiu was still obsessed with this question, and finally remembered that he still had to ask the question under Kong Haoda's reminder.

"Old decay is ugly, this question I saw from a library pavilion, to be honest, I didn't calculate the correct result.

I'll take this question out today, and I hope Xiaoyou can help me solve my worries!

Listen up!

The author of the question said that he had visited a ruin, which was circular in shape and consisted of seven bridges.

Two of the short bridges and a long bridge form the circle.

There are also three bridges in the park, which are arranged in symmetry, with the longest bridge crossing both ends. ”

As he spoke, Lin Qiu drew this diagram on the drawing, and there were a total of seven bridges to form the entrance of the organ.

"Only by passing through all the bridges at once, and not repeating them, can you open the entrance to the mechanism.

I've been studying for a long time, but I haven't been able to finish it all at once, and I've asked my friends to teach me. ”

Wu Cheng glanced at the pattern, "Impossible, no one can walk the seven bridges in one go without repeating it." ”

The reason why Wu Cheng dared to be so sure was because he had seen this question, which was a very famous Seven Bridges problem.

And after countless people hit the wall and come to the conclusion, no one can walk seven bridges in one go without repeating.

Wu Cheng's answer made Lin Qiu and the others stagnant, because the answer given by Wu Cheng was too incredible.

There must be an answer to any arithmetic question, otherwise wouldn't the question be meaningless?

For example, if there is no solution to the mechanism corresponding to this problem, it does not mean that this mechanism is useless and useless.

But if it really has no use, then what is the point of its existence? Just to make fun of these juniors? It's not scientific.

But since Wu Cheng said this, Lin Qiu didn't look anxious, but lowered his posture and asked, "I don't know why Xiaoyou said this?"

This seven-bridge problem appeared in the summer vacation homework of primary school students in China, and the seven-bridge problem at that time was reduced to a single stroke.

Therefore, Wu Cheng is no stranger to this problem, and immediately began to explain......
