Chapter 291: Xu Mang

The next day,
This day is destined to be extraordinary.
Xu Mang followed Xiaoman to the scene of the game. Because there was still an hour and a half before the start of the game, Xu Mang, as the teacher of the team, was sitting in the corner playing with his mobile phone, and Yang Xiaoman, who was suspiciously calm, was next to him.
"..."
"I said you bastard, can you care about others?" Yang Xiaoman pouted, and said with a displeased expression: "You know that playing Hearthstone is fine. You can't win a game. .. What else can you do?"
"???"
"What can I do?" Xu Mang said helplessly: "How do you think it is easy to be a gifting child?"
"Humph!"
"Tomorrow is the closing ceremony and the awards ceremony. You have to make a good relationship first, in case you can't get in again." Yang Xiaoman said: "I think you went to National National Taiwan University very hard in the past two days. I guess I know a lot of people. , There should be no problem, right?"
Yang Xiaoman knows Xu Mang very well, and she dare not say anything else, but this ability that is close to others is unparalleled in the world. Although most people hate him, it can be regarded as remembered by others. At least there was a subtle connection between the two.
"Oh..."
"I've done it." Xu Mang said absently: "I mentioned it to Deputy Director Zhou of the Department of Materials yesterday. He should explain the situation to the school."
"How do you know the deputy director of the National Tsing Hua University Materials Department?" Yang Xiaoman asked curiously.
Xu Mang said indifferently: "Have you forgotten that I am the developer of the materials science database? All the teachers and students in the Department of Materials Science and Technology of National Tsing Hua University use the things I developed. I have a lotus root with them that cannot be cut."
Yang Xiaoman gave a blank look, took out his phone and started to scan Weibo.
quickly,
Game start,
The fourth player of the team competition comes on stage and the game time is three hours.
Now Xu Mang has not paid much attention to the so-called results. Now he only sees how to win this round of Hearthstone, let alone... the number of player routines these years is hard to defend.
It's only seven fees,
Xu Mang was blown up by others.
"What a boring game!" Xu Mang sighed, silently put away his mobile phone, looked around the scene, and found a group of people not far away.
"Uh..."
"Xiaoman?" Xu Mang asked curiously: "Look at that, there are many people around, did something happen?"
"Yes."
"What are they doing?" Xiaoman was also curious about this, and said: "Should we go and see?"
Words fall,
The two went to the scene of the incident.
When I got there and asked, it turned out that a group of mathematics teachers and students were calculating the possibility of the password of the abandoned safe. There are ten numbers from zero to nine. The password is a four-digit combination of these ten numbers. Each person has only one chance. Try to unlock.
Is this a boring teacher who temporarily remembered such a game? It just so happens that there is an abandoned safe on the scene of the game. Life is such a coincidence!
Not to mention,
Attracted countless students and leading teachers.
This is a complete game of probability, because this lock can be opened with a probability of 10,000, but it still does not prevent these teachers and students who are good at math from cracking it.
unfortunately,
Fifteen people tried, all of which ended in failure. At this time there are nine thousand nine hundred and eighty-five possibilities.
"Ugh?"
"What should I do?" Yang Xiaoman asked Xu Mang next to him secretly: "Can this be calculated by a mathematical model?"
"are you crazy?"
"You really think that mathematics is omnipotent?" Xu Mang said helplessly: "I'm thinking of using non-mathematical methods to crack. Have you seen the worn buttons on the safe? I think the secret of cracking lies on the second, seventh, and nineteenth. , Zero and four numbers."
"what?"
"Is there any wear?" Yang Xiaoman looked at the four buttons with a confused look, and found no signs of wear, but... it was just a little faint.
"Humph!"
"Do you think everyone said that my golden eyes were fake?" Xu Mang showed disdain: "Of course... the golden eyes sometimes fail."
Xu Mang did not dare to say the second half, he was afraid that Yang Xiaoman would explode in place.
Yang Xiaoman gave him a white look.
cut!
It's still a golden eye, it's obviously a thief!
After this,
Ten more challengers have challenged, and then all have failed.
"There is only one chance to try, a little too little... Let's change to three times!"
"Change to three times!"
"I also think it is interesting to change it to three times."
Because of the unreasonable mechanism, many people present were dissatisfied, and these dissatisfied people were eliminated, so the game initiator was not allowed to change his mind, and the rule was still implemented.
who knows,
This attracted too many players to join the game.
It may be for the gambling head, the initiator actually paid for it out of his own pocket, threatening that who could crack this abandoned cipher cabinet at a time and transfer a five-yuan red envelope on the spot.
five yuan!
Many leading teachers are moved by it. As a married man, five dollars is an astronomical figure!
"Ugh!"
"So stingy!" Yang Xiaoman said with a look of contempt: "Five yuan...is it worth losing so many brain cells for five yuan?"
"..."
"Ask you!" Xu Mang said with a serious face: "We will get married in the future, who will take care of the family's money?"
"nonsense!"
"Of course it's my mother!" Yang Xiaoman glared at Xu Mang, and said fiercely: "What? Any comments?"
"Then how much pocket money do you give me a month?" Xu Mang asked.
"Five yuan!" Yang Xiaoman gave a number immediately without even thinking about it.
"..."
"Look... five yuan, this is the monthly living expenses of the teachers!" Xu Mang sighed and said with a heartbreaking expression: "Can you say they can't be excited?"
Yang Xiaoman: (′▽`〃)
This seems to be the case.
"Ugh?"
"You are better than them." Yang Xiaoman said embarrassedly: "I give you 50 cents every month."
Ugh...
So angry!
How did such a handsome young guy fall into Xiaoman's hands?
Xu Mang sighed and refocused his mind on the game of deciphering the code, two, seven, nine, zero...what is the difference between these four numbers?
at this time,
Xu Mang thought of an extracurricular book "Behavioral Psychology" that he had read because of boredom in high school in the past. Not to mention that Xu Mang's skill in cutting leek is so good, it is really inseparable from the book "Behavioral Psychology". .
Although he does not have psychological skills, his past memories still exist. Xu Mang decided to explore from the perspective of the password input person and from the psychological aspect of behavior 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 your finger.
Since the contact surface with the finger is kept maximized, there is only one result in the end. The math button on it is the most worn out, which button is the weakest?
zero!
Zero wear of buttons is the most powerful!
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. The movement of the finger will be the key to the second password.
Seven,
The upper left is somewhat dim.
nine,
It's a little dim above.
two,
Can't judge temporarily.
Xu Mang's brows were frowned at this time. According to the behavioral logic of the person who entered the password, and the characteristics of the password buttons' stress and wear, the second password should be seven.
The upper left side of the button seven is worn badly, and the force point of the finger is on the upper left side, so it is assumed that the finger moves from the right to the upper left, otherwise the force and wear characteristics cannot be obtained, and the layout of zero and seven is just in line with my guess.
So far the second password is seven!
nine...
The force and wear characteristics are on the top, so only the moving track from top to bottom can cause such a situation, so it is speculated that the third password is two, and only when the finger presses two can it move from top to bottom to nine.
and so,
The password is zero seven two nine.
"Ugh?"
"Did you think of the password?" Yang Xiaoman suddenly asked with a smile, "Are you stumped? Faced with such a clueless situation, do you feel that the knowledge you have learned is useless?"
"such!"
"If you can crack the password cabinet at once, get the five yuan red envelope from that teacher, and get married in the future, you will be in charge of the family's money!" Yang Xiaoman said: "But the challenge is not successful, then I am sorry... .You don’t even have a small vault."
Xu Mang sighed.
Xiaoman na Xiaoman,
Why are you so young and cute?
"how?"
"Don't dare to accept the challenge?" Yang Xiaoman saw Xu Mang's silence and suddenly became interested, and immediately decided to give Xu Mang a little more discount.
"Ugh!"
"I will give you more effort. We will get married in the future. You can have two days a week to play games all night." Yang Xiaoman said with a smile, "How? This condition is very attractive to you. Power?"
hiss!
God!
Is this a risk?
Xu Mang was taken aback, and he decided to teach the cute and ignorant Xiaoman.
"Little Man..."
"Do you know why my grades in the first and second year of high school are so poor?" Xu Mang asked solemnly.
"what?"
"Uh...maybe lazy?" Yang Xiaoman said, "it could also be really stupid."
Xu Mang: @#￥%……
"Forget it to be honest with you, I read a book "Behavioral Psychology" in high school, which changed my life a lot." Xu Mang said with a grin: "Most of the theory of cutting leek is based on this. This book is here."
Yang Xiaoman looked confused and asked curiously: "Is there any direct relationship between "Behavioral Psychology" and your attempt to crack the code?"
"I just simulated the order of the passwords based on the force and wear characteristics of the password buttons." Xu Mang said indifferently: "I didn't mean that the password buttons were a bit weird, two, seven, nine, zero, four The password buttons are severely worn, and the password is the sequence of these four numbers."
"But it's useless to know, because there is only one chance, I don't really believe in the probability~EbookFREE.me~ so I guess based on the characteristics of the force and wear." Xu Mang said: "Zero is the most severe of the four buttons. Yes, the first password is zero."
"There is abrasion on the upper left side of the seven, which is caused by the movement of the finger from right to the upper left. Therefore, the second password seven and the password nine are worn on the top. There is only one possibility. The fingers move from top to bottom, so the third The password is two."
"Final password, zero seven twenty nine!" Xu Mang showed a very awkward smile: "My name is Xu Mang, and I am a master of behavioral psychology!"
Words fall,
With Yang Xiaoman's horrified expression on his face, Xu Mang walked to the center of the crowd, squatted down, and silently pressed the code sequence of zero seven twenty nine.
Suddenly,
I heard a ‘click’ sound.
So far,
The abandoned cipher cabinet that had troubled everyone present for an entire hour was relentlessly opened.
