Turing Forbidden Zone

Everything runs smoothly.

黑色巨龙首将内容传递进塔的内部：【学号是18111439，密码是123——或1+1=2。】

Then the white giant dragon looked for documents that met the requirements.

For every document it looks at, it is judging: [Student number is 18111439? 】

Until I found the matching one - the document with the student number 18111439.

Then it judges: [The password is 123? 】

Incorrect, marked as 0.

Then it judges: [1+1=2? 】

Correct, marked as 1.

所以，【密码是123或1+1=2】，即为【0or1】。

The answer is 1.

Password is correct.

The document matches successfully and is allowed to be returned.

The white dragon head passed the document it found back to the black dragon head.

Shi Ye saw this document.

[Student number: 18111439

Name: Wang Gu

Score: 129/150 points

Ranking: 6]

However, Shi Ye also didn't care about this document. What he cared about was that the white clock tower in front of him had an obvious loophole: it could be injected by SQL.

It was a simple and typical SQL injection just now.

Simply put, Shiye can log in to any account without knowing the password.

He has a master key called [1+1=2], so even the lyrebird no longer needs it.

Holding this key in hand, he bypassed the black dragon head of the guard gate, and stepped into the inside of the clock tower from the administrator's dedicated working passage.

SQL database is a classic relational database.

In front of Shi Ye, there are countless neatly arranged bookshelves, each of which can soar into the sky and hold countless books and documents.

The bookshelf in front of him was called [Final Grades]. He casually took out a document from it, and saw the transcript of another stranger from the same school.

Bypassing this bookshelf, the next one is called 【Exam Bank】.

The next one is [Original Results], which seems to be the initial running results of the program.It includes data in four dimensions: accuracy, running time, memory consumption, and ranking distribution.

Shi Ye sat down in front of this bookshelf, and ordered the white giant dragon head as an administrator: [Find the documents of student number 18111427 and student number 18111439. 】

The white giant bowed its head and obeyed, and quickly sent two pages of paper flying in front of Shiye.

[Student number: 18111427

Name: Shi Ye

Accuracy: 99.9%, 100%, 76%

Run time: 8ms, 14ms, 431ms

Memory consumption: 11.7MB, 19.2MB, 47.8MB

Rank distribution: 2%, 1%, 1%]

[Student number: 18111439

Name: Wang Gu

Accuracy: 96%, 2%, 0%

Run time: 20ms, 390ms, timeout

Memory consumption: 12MB, 70.5MB, timed out

Rank distribution: 65%, 80%, none]

Data is intuitive.

The original program was scored after the system was accepted, and Shiye's answer was the best no matter what the indicators were.

However, after manually scoring and entering from the original score, he suddenly only had 50 points left.

Shi Ye can fully understand the principle of the operation of an electronic system, but cannot understand the factors behind human participation.

Nor was anyone else in his electronic world.

The electronic wind gradually faded, and the chirping of cicadas by the window seemed noisy again.

Shi Ye connected to the printer on the second floor through the wifi in the library, and printed out the two original data obtained just now.

He got the raw data, what to do next?Do you want to question the teacher who entered the grades?

He doesn't want to talk to anyone, it's inefficient, long and boring.

So Shi Ye thought about it and opened the official website of D University.

……

The afternoon passed unknowingly.

Chu Yingzong finished another trial class, and when she was still scratching her head and thinking about how to choose the class schedule, she heard someone next to her accidentally mentioning: The Golden Lotus Cup is over, and two freshmen won the third prize.

Chu Yingzong's thoughts immediately drifted away, and he thought of Shi Ye again, thinking: Could it be this guy?

Once some things are remembered, they start to get out of hand.

Chu Ying simply put away her things, and after dinner, Shi Shiran ran to the freshman dormitory for a squat. She turned on her phone and saw that it would be 19:00 in the evening.

That's right, it's the time to go back to the dormitory every night at ordinary times.

While there was still time, Chu Yingzong turned to the building to go to the toilet.

As soon as he entered the compartment, he suddenly heard two familiar voices outside——

"What's the matter with you?"

"Well, Director Sun, after thinking about it, I still feel something is wrong..."

Chu Yingzong's ears trembled, and she recognized it: Isn't this Shiye's roommate Wang Gu, and his irresponsible counselor Sun Lezhi?

It sounded like something was up.

Chu Ying simply sat on the toilet, crossed her legs, and continued to listen with her ears straight.

Wang Gu stammered and said: "Director Sun, can I really win the third prize of the Golden Lotus Cup? Could it be something wrong...?"

Sun Lezhi: "Oh, it's yours, so take it well."

Wang Gu: "But, but, I really don't know anything, and even the questions are taught by Brother Carry. The code for the second question is basically copied from the Internet, and the third question is written blindly. It can't be correct."

Sun Lezhi said: "Don't think about it, the problem this time is already very difficult, and everyone can't solve it. You are already considered good."

Wang Gu was silent for a while, summoned up his courage, and still couldn't help but said: "I think...it must be wrong. I have a few pounds and a few taels, and I know it in my heart. I can't compare to Brother Carry, Not to mention that seniors still have special admissions. There must be a mistake somewhere, Director Sun, can you double-check it?"

This time it was Sun Lezhi's turn to be silent.

He looked at it, closed the door of the bathroom, then sighed, and suddenly asked Wang Gu: "Have you applied for the poor student allowance?"

Wang Gu said, "I applied."

Sun Lezhi said: "Among the students who applied this year, some of them have been pre-determined. Your family's situation...is actually quite serious, but this application has many...other factors, and I really can't help you get it."

"Ah..." Wang Gu uttered a syllable, and then seemed to be stunned.

crackle.

Sun Lezhi took out a cigarette, lit it, took a puff, and said, "The Golden Lotus Cup is a competition in the hospital, and the prize money is not much, but the third prize is 500 yuan anyway. The most important thing is that I can help you apply to join the laboratory. As long as most laboratories apply, they will provide you with a laptop for experimentation—you can’t even get enough money to buy a computer now, right?”

Wang Gu lowered his head.

"Some life is like a fucking script, and that's how I came here." Sun Lezhi took another puff of cigarette, and said in a slow tone, "You are just entering the freshman year, although the foundation is a bit weak, but as long as you study hard, you will be better in the future. It can be expected. If you want to learn computer science well, you need to program more and practice more. Computers are definitely indispensable. Your bonus is 500 yuan, and I will personally subsidize you with 1000 yuan. You can use it to buy a cheap one Notebook."

Wang Gu bit his lip, suppressing his choked throat and heaving chest.

After that, the room was quite quiet.

Sun Lezhi finished smoking the cigarette quickly, and opened the window to let the smell of smoke dissipate as soon as possible.

At this moment, he suddenly noticed that a compartment door was ajar, and there might be someone inside...

Just when Sun Lezhi was about to open the door, Wang Gu behind him suddenly said, "But, Director Sun. If I win the third prize like this... wouldn't someone be squeezed out?"

Sun Lezhi turned around and said with a little hatred, "You are already like this, how can you still care about others?"

Wang Gu shrunk back a little, his eyes were red, but he still met his gaze, and said stubbornly: "I am poor, but I, I don't want to lose other people's things. Maybe, maybe the real third prize is waiting anxiously." What about the bonus?"

"You can rest assured." Sun Lezhi sighed and said, "I've seen it too. If you have to say whose quota you topped, then that person has a very strong background, is not short of money at all, and wants to get in." He can enter any laboratory. This kind of competition is not worth mentioning to him. Maybe it can warn him to put on a good attitude and study hard... Otherwise, he has a very bad temper, and I can't control it at all. What the hell? What's the matter?"

At this moment, Chu Ying was sitting on the toilet, playing with her fingers boredly, a bit stuck, unable to get out of the house—I'm always embarrassed to say "surprise, I've been eavesdropping" in front of others, right?

He was stunned for a moment when he heard this.

The last few words of Sun Lezhi seem familiar?

Chu Ying thought about it for a while, and the conversation that went into his left ear and out of his right ear just now quickly formed a thread in his mind.

He came back.

"The scum of the world!"

Accompanied by a terrifying roar, the door of the compartment was kicked open!

Sun Lezhi, who was throwing cigarette butts into the trash can, was terrified. The cigarette butt burned his fingers. When he raised his head in a panic, the back of his head suddenly hit the shampoo table, making a "stick" sound.

Wang Gu was also taken aback: "I rely on...?!"

I saw a junior school grass appeared in the door like a magic weapon descending from heaven.

Chu Yingzong stared fiercely at Sun Lezhi, who was covering her head, and said with a sneer, "I'll be the one who deserves to be a counselor?"

Sun Lezhi finally straightened up, his face livid and ugly, and said: "You...you have been eavesdropping here?"

"If I hadn't happened to be here, I would have told you to lie!" Chu Ying said furiously, "The school asked you to enter grades, and that's how you entered them? You can change students' grades according to your own ideas, what are you doing?" Irresponsibility is dereliction of duty! You can’t even achieve the most basic fairness, but you still want to be a teacher? I think catching a bastard on the road is more competent than you! Don’t throw cigarette butts, wash yourself and throw it into Recycle it in the trash can as soon as possible, so as not to poison the flowers of our motherland!"

The fighting power of the school bully is indeed not covered.

He finished this sentence in one breath, like a machine gun, and Wang Gu's eyes were straightened when he heard it.

In contrast, Sun Lezhi was simply clumsy: "This, I... I am doing this for their own good. What do you know?"

"Fart! Kindness without fairness is hypocrisy, meaningless at all! You are just generous to others, wanting to satisfy yourself and move yourself!" Chu Yingzong pointed at his nose and cursed. I don’t know how to repent, I’m so mad! You just wait for me, with me, Chu Ying, around for a day, you don’t want to be a counselor for another day!”

——How could there be such a teacher?Using his power to tamper with students' grades, and thinking that it is for their own good?

Chu Ying is so angry.

I feel like every hair is standing on end!
