Dusha was sitting at the computer desk, supporting his chin with his hand, racking his brains to think about how to design his entry, and wondering what kind of software could win the championship?

He checked online and found the first-place work in the World Hacker Programming Competition.

This work is written in assembly language, with a total length of 4095 bytes. The generated program is only 4KB, but it has 3D effects and background music. It is really awesome.

He downloaded the program and opened it.

The monitor showed a passage with the ceiling light turned on. According to the introduction, he knew that this was a scene in a game called Dizzy.

Why not, I will do something similar.

Once he had an idea, he began to implement it.

This time he is going to make a 3D hunting game, and the location of the deer will be different every time.

He began to work hard. He spent a day and a night and finally finished the game. At this time, his feet were filled with mineral water bottles and instant noodle buckets. In order to repay Dusha, the friends in the dormitory did not disturb his work.

That's why his work went very smoothly.

In the blink of an eye, next week, after uploading the finished game to the programming competition entry website, Dusha walked into the bathroom and took a shower.

As long as they are students in the school, they can freely download and watch the entries on the programming competition entry website. In the end, the first, second, third, and so on will be selected based on voting.

After taking a shower and walking out of the bathroom, Dusha received a text message and knew that tomorrow was the day when the winners would be announced.

He plans to treat his friends in the dormitory to dinner again tonight.

Friends in Dusha's dormitory got the news and congratulated Dusha in advance.

"Dusa, I wish you the first place in the programming competition."

"Xiao Du, do you need a girlfriend? If so, I will introduce you to one."

"Boss Du, you are so rich, I'm so envious!"

"Boss, I admire you so much, please accept my knee!"

"Boss, from now on it's your turn to clean the dormitory, I'll do it for you, you don't have to do anything!"

"Boss, you will definitely be a great software engineer in the future."

"Boss, grandpa asked me to hang out with you, you must take me away."

Dusha had heard a lot of compliments. Although she knew they were flattering, she felt very comfortable after hearing them.

At this moment, a voice remembered in his mind.

"Novice target, hacking into the National Library of the United States of Edana database."

The game system of the god-level hacker OL has released a new task for him.

Is this the time to invade the database of the National Library of the United States of Aldana? It should be a good opportunity to practice your intrusion capabilities. Thinking of this, Dusha said to his friends: "I want to invade the database of the National Library of the United States of Aldana. Don't disturb me."

."

The friends said in unison: "I know." After they said that, they all left the dormitory, and the last one left without forgetting to close the door.

Now Dusha was the only one left in the dormitory. Dusha turned on the computer, skillfully operated the keyboard, found the website of the National Library of the United States of Aldana, and began to invade the website's database.

In Ducha's opinion, the defense system of the National Library of the United States of America database is as solid as a rock.

He must create the world's sharpest sword, the invasion tool, to break through the rock.

He began to create intrusion tools and checked the information of Dr. Lu, the founder of the database defense system of the National Library of the United States of America in Edana. He learned that Dr. Lu had a total of two books in his name.

He found the online versions of two books written by Dr. Lu - "A Brief Talk on Network Security" and "How to Build a Strong Fortress", and he began to read through them.
