Chapter 292

The next day,

is destined to be extraordinary.

Xu mang follows Xiaoman to the scene of the competition. As there is still an hour and a half before the start of the match, Xu Mang, as the team leader, is sitting in the corner playing with his mobile phone, and he is suspected of being calm.

"..."

"I said, you bastard, can you care about others?" Yang Xiaoman tooted his mouth and said with displeasure on his face: "you know how to play furnace stone, even if you play furnace stone, you can't win a set... What else can you do?"

“？？？”

"What can I do?" Xu mang said helplessly, "how do you think it's easy to be a child

"Hum!"

"Tomorrow is the closing ceremony and award ceremony. You should make good relations first, in case you can't get in again." Yang Xiaoman said: "these two days I see you go to Qingda very diligent, estimated to know a lot of people, there should be no problem?"

Yang Xiaoman knows Xu mang very well. She doesn't dare to say anything else. However, she has the ability to get close to others. Although most of them hate him, it can be regarded as a memory for others. At least there is a subtle relationship between them.

"Oh..."

"I've got it." Xu mang said absentmindedly: "yesterday, I talked to the deputy director of the materials department. He should explain the situation to the school."

"How do you know the deputy director of the materials department of Qingda?" Yang Xiaoman asked curiously.

"Did you forget that I was the developer of the materials science database?" Xu said calmly? All the teachers and students in the materials department of Qingda used the things I developed. They and I have a lotus root that can't be cut off. "

Yang Xiaoman took out his mobile phone and started to brush his microblog.

Soon,

the competition began, and the fourth player of the

team competition came on stage for three hours.

Today's Xu mang has not paid attention to the so-called results, now his eyes only how to win this round of furnace stone, not to mention... There are so many players' routines these years that it is impossible to guard against them.

When he arrived at seven fees,

Xu mang was beaten up by others.

"What a boring game!" Xu sighed, quietly put away his mobile phone, looked around the scene, found a group of people not far away.

"Er..."

"Xiaoman?" Xu mang asked curiously, "you see, there are many people around. Is there something happening?"

"Yes."

"What are they doing?" Xiaoman was also very curious about this and said, "shall we go and have a look?"

Then they went to the place where the incident happened.

When we got there, we found out that a group of mathematics teachers and students were calculating the password possibility of the abandoned safe. There were ten numbers from zero to nine, and the password was a combination of four of the ten numbers. Each person had only one chance to try to unlock the lock.

This is a boring teacher will temporarily think of such a game, just on the scene of the game there is an abandoned safe, life is such a coincidence!

Let alone,

has attracted countless students and leading teachers.

This is a complete probability game, because this kind of lock has 10000 kinds of probability to open, but still did not prevent these teachers and students who are good at mathematics from cracking.

Unfortunately,

fifteen people tried and all ended in failure. At this time, there were 9985 possibilities.

"Ah?"

"What about this?" Yang Xiaoman secretly asked Xu Mang: "can this be calculated by mathematical model?"

"Are you crazy?"

"Do you really think mathematics is omnipotent?" Xu mang said helplessly: "I'm thinking about using non mathematical methods to crack. Do you see the worn buttons on the safe? I think the mystery of the solution lies in the number of two, seven, nine and zero. "

"Ah?"

"Is there any wear and tear?" Yang Xiaoman looked at the four buttons with a confused face. He didn't find any signs of wear and tear, just... It was just a little light.

"Hum!"

"Do you think it's a fake to say I'm a flamboyant?" Xu mang face dew disdain: "of course... The golden eyes also have failure time."

Xu mang dare not say the second half of the sentence, he is afraid of Yang Xiaoman explosion in situ.

Yang Xiaoman gave him a look.

Cut!

Or what eye, it's a thief!

After that,

there were more than ten challengers to challenge, and then they all failed.

"There's only one chance to try, it's a little too little... Change it to three times!"

"Three times!"

"I think it's interesting to change it to three times."

Because of the unreasonable mechanism, many people present were dissatisfied, and these dissatisfied people were eliminated. Therefore, the game initiator did not change his mind, and the rules were still implemented once.Who knows,

this has attracted too many players to join the game.

Perhaps for the sake of the lottery, the initiator even paid his own pocket and threatened that whoever could crack the abandoned password cabinet at one time would transfer a five yuan red envelope on the spot.

Five dollars!

Many leading teachers are attracted by it. As married men, five yuan is astronomical!

"Alas

"How stingy Yang Xiaoman said with disdain: "five dollars... Is it worth losing so many brain cells for five dollars?"

"..."

"ask you!" Xu mang face solemnly said: "after we get married, who will come to the housekeeper's money?"

"Nonsense!"

"It's me, of course!" Yang Xiaoman glared at Xu Mang and said: "what? Do you have any comments? "

"How much pocket money do you give me a month?" Xu asked.

"Five dollars!" Yang Xiaoman didn't even think about it, and immediately gave a number.

"..."

"you see, five yuan is the teachers' monthly living expenses!" Xu sighed blankly and said, "can they not be excited?"

Yang Xiaoman: (′ ▽ '″)

it seems that this is the case.

"Ah?"

"You're better than them." Yang Xiaoman embarrassed said: "I give you five cents more every month."

Alas...

how angry!

How could such a handsome young man fall into the hands of Xiaoman?

Xu sighed blankly and put his mind back on the game of deciphering the code. What's the difference between two, seven, nine and zero?

At this time,

at this time,

Xu mang thought of a miscellaneous extracurricular book "behavioral psychology" that he read because he was bored in high school. Not to mention the reason why Xu Mang's leek cutting skills are so good, he really can't do without this book behavioral psychology.

Although he has no psychological skills, his memory still exists in the past. Xu mang decides to explore from the perspective of password users, from the perspective of behavioral psychology, to solve the password problem step by step.

First of all,

if you are using a safe, when entering the password... The first number should be to maximize the contact surface with the finger.

Since the contact surface with the finger is maximized, there is only one result in the end. The mathematical keys on it are most worn out. Which key is the lightest?

Zero!

Zero wear of key is the most serious!

Now there are two, seven, nine, three numbers left.

Keep thinking...

the first password is zero, and its finger is at the bottom of the password keyboard, and the way the finger moves will be the key to the second password.

7、

the upper left is a little dim.

9、

it's a little dim.

2、

it is impossible to judge for the time being.

At this time, Xu's brow is locked. According to the behavior logic of the password user and the wear characteristics of the password key, the second password should be seven.

The upper left side of key 7 is severely worn, and the stress point of the finger is on the upper left side. Therefore, it is speculated that the finger moves from the right side to the upper left side. Otherwise, it is impossible to obtain such force wear characteristics. The layout of zero and seven is in line with my own conjecture.

So far, the second password is seven!

Nine...

the stress and wear characteristics are on the top, so only the moving track from top to bottom can cause this situation. Therefore, it is speculated that the third password is two. Only when the finger presses two, can you move from top to bottom to nine.

Therefore,

the password is 0729.

"Ah?"

"Did you think of the password?" Yang Xiaoman suddenly asked with a smile: "have you been baffled? In the face of this clueless situation, do you feel that you can't use what you have learned? "

"That's it

"If today you can crack the password cabinet and get the teacher's five yuan red envelope, you will take charge of the money in the housekeeper if you get married in the future." Yang Xiaoman said: "but the challenge is not successful. I'm sorry... You don't even have a small Treasury."

Xu sighed blankly,

Xiaoman, Xiaoman,

Why are you so young and cute?

"What?"

"Dare not accept the challenge?" Yang Xiaoman saw Xu mang silent, suddenly came to interest, immediately decided to give Xu mang a little discount.

"Alas

"I'll give you more strength. After we get married, you can have two days a week to play games all night." Yang Xiaoman said with a smile: "how about it? Is that attractive to you? "

Hiss!

Oh, my God!

Is this a big deal?Xu mang is surprised, and he decides to teach Xiaoman a good lesson.

"Xiaoman..."

"do you know why my grades are so poor in grade one and grade two?" Xu asked solemnly.

"Ah?"

"Er... Maybe lazy?" "It may be really stupid," Yang said

Xu Mang: @ @ ￥%

"Well, to tell you the truth, I read a book called behavioral psychology in high school, which changed my life a lot." Xu mang said with a smile: "the theory of cutting leeks is mostly based on this book."

Yang Xiaoman looked confused and asked curiously, "is there any direct relationship between behavioral psychology and you're going to crack the code?"

"Just now I simulated the order of the password according to the stress and wear characteristics on the password keys." "Before, I didn't mean that the password keys were a little weird. The four password keys, two, seven, nine and zero, were seriously worn out, so the password is the order of these four numbers."

"But it's useless to know, because there is only one chance. I don't believe in probability very much, so I speculate according to the stress and wear characteristics." "Zero is the most worn of the four buttons, and the first password is zero," Xu said

"The wear on the upper left side of seven is caused by the movement of the fingers from right to left. Therefore, there is only one possibility that the wear of the second code seven and nine is on the top. There is only one possibility that the finger moves from top to bottom, so the third code is two."

"Final code, 0729!" "My name is Xu mang. I'm a master of behavioral psychology."

With a frightened expression on Yang Xiaoman's face, Xu mang went to the center of the crowd, squatted down and silently pressed 0729.

Suddenly,

a "click" sound was heard.

At this point,

the abandoned password cabinet, which bothered all the people present for an hour, was mercilessly opened.
