"There are four keys in it, key 1, two angels can only be one good and one bad, and you don't know which one is good and which is bad.

Key 2, the two angels will only answer 'yes' or 'no'.

Key 3, only one question can be asked.

Key 4, it's useless to just figure out who is a good angel and who is a bad angel, this is not the key to solving the problem. ”

Zhang Tingting raised her eyebrows: "Answer me now, what question did this person ask?" ”

“……”

A glimmer of light flashed in Xiang Beibei's eyes, and the corners of his mouth smiled: "Interesting, I finally encountered an interesting problem." ”

The competent man frowned, clasped his hands to his chest, and his brain quickly deduced the answer.

Liu Zixuanhe was confused by this very logical question, and thought about it for a long time without any result.

Two minutes later, the inner cow was full of faces: "I...... I can't guess. ”

Poor child......

Zhang Tingting touched her head: "It's okay, this question is very difficult, and some people can't figure it out even if they think about it for a lifetime." ”

"Really?" When I looked up, it was all tears.

Zhang Tingting: "......"

Liu Zixuan rubbed his temples: "I can't think of it, I can't even tell which is a good angel and a bad angel, how can I know which is the way to heaven?" Can you ask two questions? ”

"What do you say?" Zhang Tingting smiled: "Your head just won't turn, you!" It's better to be your soldier and charge into battle! ”

Liu Zixuan was speechless.

Zhang Tingting turned her head to look at Shangsheng and Xiang Beibei, who were sitting together. The competent man was still closing his eyes and meditating. Scooping a Parker pen to Beibei, writing and drawing on the notepad, frowning and comforting when showing off her eyebrows, and sometimes stopping to meditate.

"Did you two come up with it?" Zhang Tingting didn't want them to guess it, especially Shangguan people.

This pair of dog men and women are extremely smart demons, as long as the two of them are given enough time, Zhang Tingting doesn't think they will not be able to guess, so appropriately interrupting the two people's thoughts is the way to win.

Xiang Beibei stopped writing and looked at her, and smiled: "Wait a minute." Got a little clue. ”

Shangguan Nengren opened his eyes: "It's still a little close, it'll be fine right away." ”

The answers of the two made Zhang Tingting suddenly nervous: How is this possible? It also took me three days to come up with the answer, how could they be so fast? Forget about the powerful people, can't I compare to Xiang Beibei?

"Do I want to give you three days to think about it?" Zhang Tingting said casually.

Xiang Bei smiled and said, "No need." Just give me ten more minutes. ”

Shangguan Nengren pouted: "It takes three days to think about this?" How stupid does that have to be? ”

Crackling -

Zhang Tingting's forehead was bruised, and she couldn't wait to fight with him.

Shangshang's capable people closed their eyes again, only to think that this reasoning question is really interesting, not only very logical, but also reveals a kind of cognition of human nature, a good angel who can only tell the truth, and a bad angel who can only tell lies, but without knowing it, only one question can be used to derive the direction of the path to heaven, which is really interesting.

Xiang Beibei also found this logical reasoning question very interesting. For her, who has an A-level smile and a hidden knife, this kind of topic that reveals her cognition of human nature is really too appetizing for her.

Three minutes later, Xiang Beibei stopped his pen and smiled, "I know." ”

Almost at the same time, Shangguan opened his eyes and said with a smile: "I know it too." ”

The two turned their heads to look at each other and smiled.

Zhang Tingting chuckled in her heart and pretended to be calm: "Since you guessed it, let's say the answer!" However, to prevent one of them from cheating. You'd better write out your answers and give them to me to compare. ”

"Cut! You are living the belly of a gentleman with the heart of a villain. "The contempt of the competent people almost made Zhang Tingting crazy, if there was a slight rush in his hand, he would have to be killed suddenly. …,

Xiang Beibei tore off a piece of paper, and Xiang Beibei's answer was recorded on this paper. Then he handed the notepad and Parker gold pen to the competent person: "Husband, it's your turn." ”

"Trouble." The competent person took it. Brush brush brush quickly write the answer in the notebook and tear it off: "Scoop it!" ”

Zhang Tingting glanced at him fiercely, the answer of the two was in her hand, and then she compared it, and her face gradually became ugly.

"How? What's the answer? Seeing that Zhang Tingting was silent for a long time, Liu Zixuan asked a little impatiently.

"Sister Tingting, show me too." urged.

Zhang Tingting silently handed the answers on the two pieces of paper to Liu Zixuanhe, looked at Shangguan and Xiang Beibei gloomily, and said, "You won." ”

Shangguan Nengren smiled and said, "Of course." ”

Squinted at Bei Bei and smiled.

Liu Zixuanhe looked at the answer on the paper, and Shangguan Nengren's answer was very straightforward: he pointed to a road at random and asked the two angels, "Do you think the other party will say that this is the way to heaven?" ”

This answer made Liu Zixuanhe not understand for a while, but after looking at Xiang Beibei's answer, both of them understood.

Suppose the road names A and B are asked at the same time: Do you think the other angel would say that Road A leads to heaven?

Situation 1: If a is the way to heaven, the good angels will answer 'no' and the bad angels will say 'no'.

Situation 2: If b is the way to heaven, the good angels will answer 'yes' and the bad angels will answer 'yes'.

That is to say, after this question is asked, as long as all the angels answer 'no', A is the way to heaven, and they all answer 'yes', and B is the way to heaven.

"I see." Liu Zixuanhe thought about it for a while, and all understood, Gao! That's high!

Good angels will only tell the truth and bad angels will only tell lies, so that as long as the two angels know what the other will say and draw results from their mouths, they will also know the correct answer.

If a is the way to heaven, the good angel knows that the bad angel will definitely say 'no', so the good angel will definitely say 'no', and the bad angel knows that the good angel will definitely say 'yes', so he, who can only tell lies, will only answer 'no'.

And if b is the way to heaven, the good angel knows that the bad angel will definitely lie and say 'yes', so the good angel's answer becomes 'yes', and in the same way, the bad angel knows that the good angel will definitely say 'no', so he can only lie and say 'yes'.

To sum up, if you ask for directions by pointing to a, as long as both angels answer 'no', then a is 'yes', and if both angels answer 'yes', then a is 'no'. Interesting, right?

It's interesting, it's just a waste of brain cells, and the brain can't turn and faint early (Panda wrote that this is also dizzy...... ）。

Liu Zixuan rubbed his temples and said with a wry smile: "When I saw the answer, my head was dizzy, this question is really difficult." ”

Hehe smiled: "It's okay!" This question is really interesting, it doesn't matter if you don't know, as long as the two angels know, attack the shield of the son with the spear of the son, Brother Shangguan and Sister Beibei are so smart, such a difficult problem can be solved in minutes. ”

Xiang Beibei smiled slightly: "The way of employing people is to keep one mind." After all, a person's ability and energy are limited, in the face of an unfamiliar field, you don't need to know so much, and it's too late to re-learn, so simplify the problem and let people who understand this field do it, you just need to hold a good direction and make the best use of people's talents, that's fine. ”

For example, Liu Bang, the founding emperor of the Han Dynasty, is a big hooligan, does not farm, is not filial, idle, and does not succeed in martial arts.

It doesn't matter if I don't understand, someone just needs to do it, I just need to give these things to those who can do it, and let these people be responsible for me alone. …,

With this way of employing people, the big hooligan Liu Bang set the 400-year history of the Han Dynasty.

Of course, there are negative examples, Zhuge Liang, who has been recited through the ages, is that this gentleman really doesn't know how to use people! The power is monopolized, and everything that rises to the top of the five boards has to be handled by himself, and as a result, his subordinates cannot be trained, and no one is available in the later period of the Shu Kingdom, but Zhuge Liang himself is tired to death, which is really ironic.

Shangguan clapped his hands: "Bei Bei said it too well, just like today's pig association, a group of stupid pigs don't understand fart, but laymen lead insiders, making the national pig generation not as good as the generation, and if it goes on like this, I am afraid that the national pig will gradually degenerate into a bed bug, the cow herd Feng Gong's "Thief Company" has said, the layman leads the insider, and no one is not in trouble." Chinese football is ruined at the hands of these laymen. ”

After speaking, Shangguan turned his head to look at Liu Zixuan: "Why don't you meddle with such a big force as your Liu family?" What do you think Chinese football has become of now? ”

Liu Zixuan rolled his eyes and said, "What does it matter to me whether Chinese football is disgraced or not?" I don't look at it, and besides, our Liu family is a military family and doesn't interfere in government affairs, what's the use of you telling me. ”

Oh, yes! It's just three generations of an army, what's the use of saying it?

"Alas!" Shangguan can look up to the sky and sigh: "It's over, it is estimated that there is no hope for Chinese football in 20 years." ”

"Not necessarily!" Liu Zixuan smiled and said: "President Xi is a fan, as long as he says a few more words, at least there is hope for the next ten years." ”

"I'm just afraid that there will be policies and countermeasures." Shangguan shook his head: "The people below are complaining and saying that they can't do a good job, with the current environment of Chinese football, what can President Xi do?" Unless President Xi puts China's foot? p>

"......" Liu Zixuan scratched his head: "I said, how can you talk about Chinese football?" Your thinking is too divergent! ”

"Oh? Hehe......" Shangguan Nengren smiled, turned his head to look at Zhang Tingting, and sneered: "Tingting, I answered this question, what did you say just now?" Hey, striptease ......"
