A password is a form of expression in which ordinary numbers or letters are covered with corresponding means to hide the original information.
To put it bluntly, although cryptography is not the favorite of all mathematics students, because its decryption method is similar to that of Sudoku, it is based on certain rules for deciphering and exploration, and it is somewhat pastime.
So when you have nothing to do, You Sheng's favorite games are passwords and Sudoku.
As long as you like Sudoku, when you see this string of numbers and Julius Caesar appearing at the same time, you will naturally understand something in your heart.
After all, the Caesar cipher can be regarded as the most basic encryption method in cryptography.
The program group's prompt was so obvious, and the statue of Caesar was directly placed in front of him, naturally they wanted to imply that the numbers on the piece of paper were related to the Caesar cipher.
But after all, the Caesar cipher arranges the ciphers in a "displacement" manner, and the number of digits of this displacement is uncertain.
There are 26 letters in English, so there are 26 ways of changing and shifting.
It is not known how long it will be pushed like this, not to mention that he is still not sure that the password on this piece of paper is the final answer.
The situation in front of him doesn't look clear, but You Sheng is not in a hurry.
Not to mention that the other two people probably don't know what the "Caesar Code" is, and there is no way to crack new clues through the code, so there must be other mysteries hidden in the library on this floor.
Even if the program group trusts them very much and confirms that they can unravel the meaning behind this string of weird letters, it is absolutely impossible not to give any hints of displacement.
Unless they were rushing to get them on the "fruit home page failure list" result from the beginning.
Since it is a displacement, it is naturally related to numbers.
Although there is a lot of information related to numbers in the library in front of you, You Sheng decided to start with the very first information.
After arriving at the library, the director announced a bunch of dos and don'ts.
But only one sentence, involving numbers.
That's the sentence-
"Currently, the violations of the three of you are as follows. You Sheng once, He Younan once, and Gu Fengqing twice."
Regarding the violation of the three people, the director just reminded them once not long ago, so why repeat it again and again.
What's more, they are naturally very clear about their own number of violations, but they don't need to know the number of violations of other people at all.
After all, they are now on different floors, so what if they know that the number of violations of other people is close to three?
Of course, these are just You Sheng's guesses.
However, his number of violations is 1, which is the simplest number of displacements, and it is also in line with the program group's consideration of program effects.
So he's definitely going to give it a try.
Displacement is divided into forward displacement and backward displacement.
JUFISQSOIUJEBU.
First try to move backwards once, and the number of shifts is one, and this string of messy letters becomes——
ITEHPRRNHTIDAT.
It still looks like nothing has changed.
but......
You Sheng smiled.
The program team really didn't mean to embarrass them.
This string of passwords is already very clear, and it is not a difficult password.
It is another basic password conversion method in passwords-fence password.
And it's the easiest two-column password.
Divide it in half from the middle, ITEHRPR, NHTIDAT.
Then rearrange the combination in order, and it becomes——
INTHE THIRD PART.
INTHE THIRD PART.
in the third area.
All these combinations were completed in You Sheng's mind, and it took only 2 minutes.
From the perspective of the onlookers watching the live broadcast, this person just picked up the piece of paper and looked at it twice.
His expression didn't seem to change, and he didn't make any calculations or pondering actions. Even the pen and paper put on the bookshelf by the director's team didn't come in handy.
Just when everyone was still struggling with what the letters on the paper were, and some even suspected that they were not English letters at all, this person had already gently put the paper back to its original place, and raised his eyes and smiled casually.
This smile is extremely flat.
But it was like the last piece fell on the chessboard, and in the blink of an eye, the winner was already divided.
Naturally, Gu Fengqing and He Younan didn't know that You Sheng had unlocked this weird password.
He Younan hadn't even discovered the piece of paper hidden behind the plaster.
The plaster looked so scary, of course He Younan didn't dare to take a step forward to examine it carefully, so he had to avoid the plaster and the horror novel in front of him, and ran to observe in other directions.
But the situation in front of him was so weird, he was timid to begin with, and after experiencing these horrific scenes repeatedly, he actually didn't have any intention of deciphering it.
In front of the camera, the director who was observing the indoor situation also rubbed his eyebrows helplessly, and complained to the executive director beside him with a painful face: "Why did you ask him to go to the fourth floor?"
Only the fourth floor has horror novels, and this person is well known for being cowardly, so why make the show so inhumane!
The executive director is also full of grievances.
Of course he knew this truth, so according to his arrangement, He Younan should be taken to the third floor and You Sheng should be taken to the fourth floor.
But at that time, He Younan resisted too fiercely, and the man in black took care not to let him run away, but in the end, he got an extra layer.
As soon as the man in black next to You Sheng saw He Younan and the others went to the fourth floor first, they naturally turned to the third floor in a clever way.
After all, the executive director doesn't want to take the blame! "The source of evil" is clearly He Younan himself!
The director waved his hand weakly, and didn't even want to say anything, so he could only keep his eyes out of his mind, and turned his head to look at the live broadcast of Gu Fengqing's situation.
Although Gu Fengqing is a girl, she has always acted vigorously and swiftly, and has always followed a neutral and neat line, so naturally she will not be frightened by such a trivial matter like He Younan.
When she suddenly saw Julius Caesar's plaster cast, although Gu Fengqing was stunned for a moment, she quickly sensed the program crew's intentions.
After all, it is strange that there is no special purpose for such incompatible things to suddenly appear in this kind of library.
Now that the plaster has been noticed, it is only natural to notice the note with the letters on it.
But......
But she couldn't understand.
It is completely incomprehensible.
It didn't even occur to her that this would be a code.
"It's not English?" Gu Fengqing thought about it carefully. Although her English level is not good, she can also see that the words written on this paper can never be English words. "Could it be pinyin?"
She tried to read it, but still couldn't get a clue.
"What the hell is this? The program team will never test us with a language that is not commonly used?"
Although I don't know the meaning of this string of letters, Gu Fengqing also thought of what You Sheng thought of before.
It is impossible for the program group to only give them this path.
This letter looks so complicated, it is very likely that it is not within the scope of her knowledge reserve, and the program team can't embarrass her like this.
Unless there are other decryption methods arranged, the note in front of him is just a choice to solve the mystery.
Gu Fengqing immediately put down the note in his hand, turned his head to look at the orderly bookshelf in front of him and the neatly arranged books on it.
The shelf next to her is full of biology-related books. Although the names are all in Chinese characters, she can still understand them.
But she picked out a few books at random and flipped through them, but the content gave her a very headache.
It seems that it has nothing to do with the book itself, so where should the relationship be...
She has searched the entire floor, and there is no clear reminder like the note after the plaster.
If it was related to the plaster itself, she had no idea anyway.
It is impossible for her to read all these books...
In other words, the director team may have given hints before this.
After all, three hours will pass quickly, and they are recording a program.
If they have no clue from the beginning and can only wander around in place, how will the ratings of this show be reduced...
But hints, what hints can there be?
Gu Fengqing raised his head with a headache, and inspected the entire floor again.
Then, his eyes suddenly paused.
Is it...
it is this? ? ?
Seeing that both Gu Fengqing and You Sheng have made progress, the program is advancing step by step along with their progress.
The barrage army that was being broadcast live by the two onlookers has naturally entered the most exciting moment.
[The barrage of You Sheng's live broadcast interface]
"Is it that Youyou can't figure it out? Why did he put the note back?"
"How could it be impossible to figure it out? His smile just now is clearly the winner's smile?"
"I agree, Youyou obviously already knows the result."
"Ah! Youyou is gone! He must already know the answer, and the direction of progress is very clear!"
Gu Fengqing's live broadcast interface is also in a similar situation.
At first seeing Gu Fengqing didn't seem to have any idea about the letters on the paper, the fans were also very anxious, but when everyone saw that she seemed to have a new idea, they felt relieved a lot.
Although I don't know what my idol is thinking, but it's good to have an idea!
Because let's be honest...
Sitting in front of the screen and watching the live broadcast, they are really...
I have no idea at all...
[The barrage of Gu Fengqing's live broadcast interface]
"I always feel that if I participated in this program, there would only be eleven big words in my mind-'Who am I, where am I, and what's the situation?'"
"Me too, don't talk about the note, I probably wouldn't think of going to see if there is any hint in the plaster!"
"So our Fengqing is so smart! Does she already have an idea?"
"I feel the same way. I used to think that Song Song is smart and Qingqing is so cute, but now I find that she is actually quite smart."
Yes, in such a completely enclosed and silent environment, people's spirits are prone to high tension.
What's more, there is a time limit added.
It is not easy to keep calm in such an environment, and they still have to eliminate tension to find clues.
It's really rare.
In such a "mental test" session, other live broadcast rooms are about to explode.
Only He Younan's live broadcast room was very quiet.
There is no way not to be quiet.
Because their idols are too quiet.
He looked at He Younan who was pretending to be dead while tucking his knees against the bookshelf on the screen.
Fans: "..."
Brother Yao, we have nothing more to ask of you, but you should make a move...
It looks like this...
Just like a still picture! ! !
The author has something to say: Fans: "I don't ask you to be as smart as MAJ's gang, but at least you shouldn't be so stupid, okay?"
He Younan: "I'm so tired...Suddenly realized that the floor I'm on is actually the fourth floor...I can't live..."
Director (silently looking at the executive director)
Executive Director: "Why are you looking at me! I've already said it's not my fault! I'm innocent!"
