Chapter 173

Teng teacher got the paper, looked at the title, all the text, no number, can not help but more curious.

After a rough reading, Mr. Teng understood the mystery. In fact, it is not the key whether the green headed people jump into the sea, but whether the tourists' words have an impact on the people on the island.

Of course,

tourists' words are not the point, the point is that... The tourists deliver a message.

What a surprise!

Xu Mang's question is so tricky!

Good!

Because of Xu Mang's title, Teng got a new inspiration. Maybe Olympic mathematics can be done in this way, focusing on logical thinking, rather than just considering the skill. Which player can participate in the provincial Olympic Games is not outstanding in skills.

"Professor Teng?"

"Brother Xu Mang's topic... Is it too difficult?" Jin Leilei asked.

"Not bad."

Teng looked at the five people present and said quietly, "I don't have to go to class. You can figure out the mystery of this question for me these days."

Clam?

No... no class?

A few people were surprised, but there was no way to do it. They could only follow the orders in silence.

Teng teacher left, he saw Xu mang out of the topic, had a wonderful idea, let Xu mang join the next provincial Olympic Games team members.

...

"are you going to die?"

"I want you to go wild. What are you doing for me?"

"Into the grass, into the grass!"

Xu Mang and Yang Xiaoman play the glory of the king in the room. As before, Yang Xiaoman will become extremely irritable once he comes into contact with competitive games. All kinds of unpaid behaviors of Xu mang are scolded by Yang Xiaoman.

five minutes later,

Xu ran was kicked out of bed by Yang Xiaoman tiktok. He sat alone on the toilet and shook his voice.

Women...

Xu sighed, especially for women like Yang Xiaoman. Their emotions become a little too fast. They are like blue sky and white clouds, and sudden storm in clear sky. There is no place to avoid, which is always unexpected...

jingling!

"Hello?"

"Xu mang!" "Do you know where my office is? At the end of the third floor, can you come over now? "

"Oh..."

Xu mang opened the toilet door and called to Yang Xiaoman: "Xiaoman... Mr. Teng asked me to go to his office."

"Go away!"

Yang Xiaoman is still angry. He was sure to win the last game, but he was distracted by this guy. He has a strong desire to win the game. This is absolutely unbearable.

Soon,

Xu mang arrived at Mr. Teng's office. He pushed the door and saw that Mr. Teng was working.

"Sit down."

"Oh."

After a few minutes,

after Mr. Teng finished his work, he looked up at Xu Mang and suddenly said with a smile, "Xu mang... I can't imagine that you are hiding so deep. The topic is OK. I've already seen it. It's a bit deep and interesting!"

"Of course

"Genius." Xu mang one face complacently said: "Teng teacher is not my bragging force, our school final examination of mathematics papers are all out of me, you guess how many points of the whole school?"

"..."

teacher Teng takes a look at Xu mang. According to the questions he gave in the morning, it's estimated that... Is it difficult?

"Seventy points?"

"Mr. Teng... Am I the one who failed my classmates?" Xu mang said solemnly, "am I such a heartless and shameless person? Everyone is going to celebrate the new year. I can't do it with emotion and reason! "

Teng teacher Leng for a moment, he is so heavy emotion heavy righteousness person?

"That..."

"29:9." Xu mang said with a smile.

"..."

sure enough!

You are such a person!

Teng said with a wry smile: "Xu Mang, since you are so good at writing questions, do you have any ideas? The next provincial Olympiad title, you attend the deputy leader of the team, responsible for the review and question type trend

Xu mang was stunned for a moment and asked curiously, "then I will study in the Mathematics Department of Jiangda Institute of technology?"

"It's OK!" Mr. Teng nodded.

"Not good!"

"But it's OK." Xu mang said with a smile, "I join in!"

"That's settled. I have your contact information." Teng looked at Xu mang seriously: "Xu mang... You really don't come to our mathematics department?"

"Well."

Once again heard the reply, Teng teacher is very sad, helpless... I would have been heart to the moon, but the moon shines on the ditch.

With each passing minute and second,

Xu Mang and Yang Xiaoman will be back in Ningshi the day after tomorrow.In the afternoon of this day,

Xu mang came to the classroom of the provincial Olympic team. He was going to give Jin Leilei a final lesson. Of course, Yang Xiaoman also followed him.

"Brother Xu mang..."

"publish the answer!" "We feel like we're going to die," Jin said painfully

"Yes... Brother Xu mang."

"Publish the answer."

The cry for help came like a tide.

[Ge Junzhuan 2.0 - done! ]

[get upgrade card * 10]

Xu mang sees the system prompt that the task has been completed, and it is almost time to publish the answer.

"What do you want to know?" Xu asked.

"Did visitors' words bring results?" "We want to know about this," Jin said

"Yes!"

Xu mang nodded and said solemnly.

At this time,

the only female player in the team raised her hand and said, "brother Xu mangge, before the tourists came, did the islanders know that there were people with green heads? They not only know that green headed people are there, but also that there are 99 people with green heads. What is the result if they can visit? "

"It's simple."

"I know you are a green head, I know Jin Lei is a green head, and I know that less than is a green head... I always know that the ninety ninth person is a green head, but I don't know that I am a green head." "By analogy, tourists will know that there are people with green heads on the island," Xu said

The five people below were confused.

"Maybe it's hard for you to understand now, Mody relationship!" "The simplest case is that... If there is only one person on the island with a green head, then the result of tourists' words is that he doesn't see other people with green heads, so he jumps into the sea the next day."

"If..."

"there are two green headed people on the island, I and Jin Lei Lei." Xu mang pointed to himself and Jin Leilei: "at this time, tourists' words will not bring results, because Jin Leilei and I can see each other is a green top, but I don't know whether Jin Leilei knows that I am a green head, and Jin Lei also doesn't know."

"But the tourist made a speech... His speech brought about different results, because I know that Jin Lei also knows that there are people with green heads on the island. What kind of results will this bring?"

"I'll wait a day to see if Jin Lei can jump into the sea. If not, it means that Jin Lei has also seen a person with a green head." Xu mang pauses for a moment and continues to say: "I know that there are no other people on the island who are green headed except me and Jin Lei Lei. The only person who Jin Lei can see is me."

"Do you understand?" Xu mang said with a smile.

Yes!

Seems to touch the threshold!

After Xu Mang's explanation, the five members of the provincial Olympic team suddenly realized, but it's a pity... It's still a little bit short.

What if there were three people on the top of the island? For example, I and Xiao and Jin Lei Lei. " "In fact, it's all the same. Tourists' words will not bring results at this time, because all three people know people with green heads. I see Xiao Xiao and Jin Leilei can see each other's eyes, but I don't know whether I am green headed or not," Xu said

"Because if I'm not a greenhead, only Xiao and Jin Lei are green heads. If I'm less than, I don't know if Jin Leilei knows that there are green heads on the island." Xu mang coughed gently and moistened his voice: "at this time, the action of tourists' speech will give me a result. I will wait for two days to see if Xiao and Jin Leilei will jump into the sea. If there is no jumping in the sea for two days, I will know that Xiao Xiao and Jin Leilei will wait for me to jump into the sea, so on the third day, the three of us will jump into the sea together."

"According to this logical thinking, we can continue to deduce until the nth greenhead."

Clear!

See the other side!

Jin Leilei several people along the Xu mang provides the idea, they roughly understand.

Then the question comes again...

why can tourists' words bring about a new result?

At this point,

Yang Xiaoman suddenly said, "do you want to know why tourists' words can produce results?"

Jin Leilei nodded.

"It's very simple."

"Because the tourists did an action - announce." Yang Xiaoman said without expression: "even if his words are known to all, however, he announced this behavior, resulting in an important difference."

"Before the announcement, we just know the content, we don't know whether others know it or not. After the announcement, everyone knows it." Yang Xiaoman glanced at five people: "the former is only a weak consensus, the latter is a strong consensus, understand?"

Jin Leilei shook his head and began to be confused again.

"Before tourists come, it is a weak consensus that there are green headed people on the island. However, after the tourists' announcement, the weak consensus becomes a strong consensus, which contains more information and leads to more consequences."

"Do you understand now?" Yang Xiaoman asked.oh

Got it!

It's too much!

Jin Leilei several people look at Xu Mang and Yang Xiaoman, eyes exude the light of worship.

"I'll give you an example of weak consensus and strong consensus." Yang Xiaoman said with a smile: "do you know the emperor's new clothes?"? It is a weak consensus that the emperor did not wear clothes, but after the children said it, it became a strong consensus. "

"..."

"..."

"

"... "

being a person is boring!

It's really boring!

Why are there monsters like Xu mangge and Xiaoman Jie in the world?

Jin Leilei's five people are speechless. Although they think there is a gap between Xu Mang and Yang Xiaoman, they never expect that the gap will be so huge.

"Brother Xu Mang, sister man?" Jin Leilei helplessly said: "you are so excellent, are you not afraid of revenge?"

“？？？”

“？？？”

The two were stunned and looked at each other.

"Are you afraid?"

"Not afraid."

"I'm not afraid."

Xu mang turned to look at Jin Lei Lei and said earnestly, "I'm not afraid, because we are the evil spirits of the black wind."

Jin Leilei: in the evening,

...

in the evening,

Yang Xiaoman stayed in Xu Mang's room and thought of a very important thing, that is, his nickname and Yang Xiaoman's nickname were too ugly.

Heifeng Shuangsha?

What a nickname!

"Ah?"

"What do you think?" Yang Xiaoman glanced at Xu mang who was in a daze.

"Wait a minute!"

"I have something to do." Xu said.

Xu mang looks at the data on his system.
