Chapter 463 If ??you want the answer, I will give you the answer
Han Jingyun glanced at everyone lightly, taking in all their expressions. He smiled sweetly, nodded slightly, and said softly: "Of course."
The stone in Han Du's heart suddenly fell to the ground. If it weren't for the public, Han Du would have wanted to hug the girl's forehead and kiss her.
This is really my sister, she saved my brother’s life!
Han Jingyun's words made Lao Zhu and others look happy, while Timur, on the other hand, had an ugly face.
Holding the last glimmer of hope, Timur looked livid, stared at Han Jingyun and said in a deep voice: "Little girl, don't talk nonsense here, or you will lose your head."
"Haha, what a beautiful woman. No matter what you said today is right or wrong, I will pardon you." Lao Zhu waved his hand and exempted Han Jingyun from all culpability, allowing her to express herself as she pleased. Moreover, she fully
I showed Timur that Lao Zhu has a real dragon-like sense of territoriality. I have the final say on my territory. You, a foreign minister, want to scare the little girl, have you ever asked me for my opinion?
Han Du looked at Lao Zhu in astonishment and said, "Your Majesty, your heart has gone to the East China Sea, right? I can't answer it, so your hand will touch your waist. Sister Jingyun will be pardoned in advance?"
'
However, with Lao Zhu's instructions, Han Du finally felt relieved. No matter what the outcome was, at least no one in the Han family would be unlucky.
Hearing this, Han Jingyun smiled and saluted Lao Zhu, "The daughter of the people thanks the emperor for his grace."
After saying that, she ignored Timur who was standing aside at all. Because her eldest brother often told her not to pay attention to what fools think, let alone what they say.
Han Jingyun stood in front of three pillars, directly facing the pillars filled with gold disks.
"Although this moving disk seems complicated, it is fundamentally based on a mathematical recursive idea." Han Jingyun, who has a temperament like an orchid, talked eloquently.
Just the first sentence made all the officials look at each other in confusion. Everyone had the feeling that I knew every word she said, but what did they mean when combined.
Even Lao Zhu moved his buttocks on the dragon chair and glanced at Han Du secretly.
Han Du lowered his head and smiled flatteringly, not daring to look into Lao Zhu's eyes. I know the recursion, but I don't know the kind of recursion the girl used. So, don't look at me, it's useless to look at me.
Lao Zhu glared at Han Du dissatisfiedly, "Trash!" and then turned his attention to Han Jingyun.
"Take this pillar as A, this pillar as B, and this pillar as C." He tapped lightly with his bare hands, as if pointing to the country.
At this time, Han Jingyun was the master of the Hanoi Tower in front of him.
"The number of layers of the disk is divided into odd and even. When the number of layers is an even number, it moves in the order of A, B, and C; when the number of layers is an odd number, it moves in the order of A, C, and B. Repeat this, no matter how many layers are moved, the movement can be completed. If there is
When there are three levels, A goes directly to C; when there are two levels, A goes to B, A goes to C, and then B goes to C; when there are three levels, A goes to C, A goes to B, B goes to C, A goes to C,
B to A, B to C, A to C.”
After Han Jingyun finished speaking, he looked at Timur and said: "If you need more, I can read out the fourth and fifth levels for you. Of course, I won't read out the rest. The number is too large.
Big, reciting them all will tire me out."
Timur's face was ashen. He did not expect that what he was worried about would happen. Not only was this woman sure of the answer, but she even explained the method.
Different from Timur's ugly face, the divine master on the side looked at Han Jingyun with his eyes shining. It soon turned into admiration, which was a look of admiration for knowledge and sages.
Timur felt that the situation was over, but even though his face turned red, he still held his neck and did not want to admit defeat.
"You just got it right about the simple layers of discs in the front. There are a total of sixty-four discs here. You said it yourself. The number gets larger as you go to the back. How can you calculate it clearly?"
Han Jingyun glanced at Timur who was still unwilling to give up, chuckled, and said, "If you insist on an answer, I can naturally calculate it clearly for you."
After that, he ignored Timur and pointed directly at the two empty pillars and said: "To solve this problem, these two pillars are the key. At the first level, the answer is one, which is two squared minus one."
Go to the first floor; when it is two floors, it is three, which is two squared minus one. When it is three floors, it is seven, which is two cubed minus one. For the next four floors, five floors, and six floors, you can calculate it yourself.
There are always as many layers as there are, and the number of moves is the power of two minus one. If you don’t believe it, you can try it yourself according to the odd-even method I just mentioned. Since you have a total of sixty-four discs,
The total number of moves required is two to the sixty-fourth power minus one. Oh, by the way, do you understand what I’m saying? Do you know how to calculate the power of two?"
Timur understood everything. Everyone present, except Han Du, no one understood what Han Jingyun said.
Only Han Du suddenly understood after hearing this, but Han Du only remembered the one who filled the chessboard with wheat, and did not expect that the same principle applies to the Tower of Hanoi.
Naturally, the divine master could not understand what Han Jingyun was saying, but he excitedly asked Timur to translate Han Jingyun's words for him. After listening to Timur's translation, although he did not know how to calculate, he had an idea.
I had a strong feeling that what this woman said was right.
Therefore, he urgently asked Timur to ask for the final answer. Because in his opinion, this was a major event related to the destruction of the world, and he could not be too eager.
Timur couldn't resist the stubborn master, so he had to ask Han Jingyun with a constipated expression: "The master asked you, how many years will it take to move all these disks to another pillar?"
"If you must have an answer, then I will give you the answer." Han Jingyun said calmly, "Please wait for me for a moment."
After speaking, he raised his head slightly and looked into the void, as if there were countless stars shining in his eyes.
When everyone saw Han Jingyun's posture, they couldn't help but think that she was playing tricks on her. After all, how could such a big number be calculated using nothing but mental arithmetic? Everyone couldn't believe it.
Only Han Du saw the girl's appearance and his eyes widened in surprise.
This is a calculation!
I just told her the method a few times, but she mastered it so quickly? No wonder she always carries an abacus with her. It turns out that she is practicing abacus calculation. And she is so confident that she can use abacus calculation.
Calculating such a huge number, it seems that her calculations have already come into play? No, it is very effective.
