Chapter 3 Learning 'Advanced Cheats'

Li Yi made some rough experimental estimates.

It was found that the ratio of time between the library and the outside world was about 10 to 1, that is to say, after spending 10 days in this library, the outside world only passed 1 day.

The contents of each bookshelf are categorized into categories, mathematics, physics, biology, history, novels, ..., all-encompassing, all-encompassing.

I don't know why, this is the alien language used in the book, Li Yi can understand it, and his memory has become very good, and it is not very difficult to absorb this knowledge.

This mysterious black tattoo not only gives itself a 'library', but also transforms its own brain?

Li Yi was surprised to guess so.

Li Yi took a book of "Principles of Multi-Core Algorithms" for in-depth reading.

Li Yi is a third-year student in the Department of Computer Science at CUHK. This book "Principles of Multi-Core Algorithms" fits his major and is just right for him to study.

There are many computer algorithms, sorting algorithms, graph theory algorithms, backtracking algorithms, character matching algorithms, flow-related algorithms, ..., etc. Different algorithms have different pertinence and characteristics. Multi-calculation rules are suitable for the development of intelligent programs. , suitable for multi-element homonuclear calculations.

...

I don't know how long has passed.

Li Yi read through the entire book "Principles of Multi-Core Algorithms" in one breath, and easily absorbed all the knowledge points of this book.

The learning process is not disturbed, the energy is unlimited, tireless, it is very easy to put in, focus on learning, the learning process is many times easier than in the classroom, and the understanding of various knowledge points is more profound.

In reality, Li Yi opened his eyes and woke up.

He picked up the phone by the bedside and checked the time.

It's only been more than half an hour, and the roommates haven't come back.

Li Yi thought and recalled carefully, and various core knowledge points of multi-core algorithms emerged very clearly.

In just over half an hour, a complex algorithm was won, which is incredibly efficient.

Li Yi was overjoyed and continued to enter the 'library' to read new books.

————

"Old Li, wake up, it's time to eat!" Zhang Haitao woke Li Yi by the bed.

Li Yi woke up, all his roommates came back, and he took his mobile phone to check the time.

It's already one o'clock noon.

Li Yi got up and took a shower.

After sending the meal money to Zhang Haitao, Li Yi started to eat. After eating, he lay down on the bed and continued to enter the 'library'.

Seeing Li Yi sleeping soundly on the bed again, Zhang Haitao and the others looked at each other and were very surprised.

"Damn it! Old Li is asleep again! This guy has been working for more than ten hours today, so there won't be any problems!" Lin Hang said worriedly.

"There must be something wrong. When he wakes up, let him go to the hospital for a check!" Zhang Haitao frowned and sighed.

The three no longer pay attention to Li Yi, write programs, read books, and do their own work.

Time flies, three or four hours have passed.

Li Yi rolled over and sat up, stretched out comfortably, his head was heavy, and he was not as energetic as he had just woken up.

Learning new knowledge for "dozens" of hours in a row is all about new programming languages, new algorithms, and professional knowledge in computing. Li Yi feels that his brain power is exhausted and he can't continue any longer. He needs to take a break.

"Old Li, you are awake. If you don't wake up, we will take you to the hospital!" Zhang Haitao turned to look at him and said worriedly.

Li Yi was taken aback and asked in surprise, "What's wrong! Isn't it okay for me?"

"You have slept for more than ten hours in a row, we are afraid that you will die." Lin Hang explained with a smile.

"I'm fine, but I'm a little sleepy, and I don't have any problems with my body." Li Yi smiled and explained quickly.

"Old Li, you should take the time to go to the hospital for a check up! In case there is any hidden disease,

Early detection, early treatment" Zhang Haitao reminded with concern.

"I'm really not sick, I know what's going on, don't worry about it." Li Yi couldn't help but comfort him quickly.

After speaking, Li Yi rolled over from the bed, went to the toilet, and then walked to the computer desk, opened the notebook, called up the experimental program, and started the experimental operation.

Li Yi put his hands on the keyboard, and a burst of keyboard tapping sounded.

In less than half an hour, Li Yi finished the programming experiment assignment in the computer class.

After learning several special algorithms and new programming languages, Li Yi has a deeper understanding of algorithm logic and programming language structure.

There is a kind of learning advanced cheats, and then looking at the professional knowledge you have learned now, the difficulty is lower by several levels, making the originally difficult programming assignments very easy, and the programming experiment assignments that used to take several hours to complete. , Li Yi spent less than half an hour and easily won it.

After finishing the programming experiment assignment, Li Yi was still in the mood. He opened the programming development tool-Visual Code. and planned to try to write a small tool by himself.

The 'crackling' keyboard tapping sound was as dense as rain.

Zhang Haitao, Lin Hang, and Liu Wenfeng all looked at him in surprise.

Soon, the three walked behind Li Yi and watched.

I saw that on the screen, lines of code continued to appear, gradually forming a complex and sophisticated program.

Zhang Haitao and the others were stunned. Li Yi wrote the program in C++, but they couldn't understand the content he wrote.

"Old Li, what did you write!" Lin Hang couldn't help but ask.

"I'm working on a small tool, a library package for adding new algorithms." Li Yi explained with a smile.

"New algorithm? What new algorithm, C++ library, Python package can't be downloaded from the Internet?" Lin Hang was slightly stunned, more confused, and asked inexplicably.

Programming languages ​​such as C++, Python, standard libraries, and data packages only provide some basic requirements, not all items, need to add new algorithms, special functions, etc., need more functions, can only rely on the introduction of third-party libraries / Bag.

The new algorithms learned from the 'library' are not found in human civilization. Therefore, to use these special algorithms, Li Yi needs to compile a small tool to store these new algorithms.

"It's nothing, I'll just play around, develop a gadget, and find something to do for myself." Li Yi smiled and made a random excuse to introduce.

"Grass! You're really free, have you done your programming?" Zhang Haitao scolded with a smile.

"Well, it's already done!" Li Yi responded with a smile without turning his head.

"It's so fast, it's alright, old Li! I've been writing for an afternoon, and I've been stuck with a bug! Can you help me read it?" Zhang Haitao was surprised and asked quickly.

"And mine, and I too. Once I run the test, I can't get through. I don't know what went wrong." Liu Wenfeng asked with a sullen face.

One duck is chasing, and two ducks are also chasing.

Li Yi simply nodded and replied with a smile: "Okay, bring them all!"

Hearing this, Zhang Haitao and Liu Wenfeng hurriedly went to get their notebooks, and then showed the experimental code to Li Yi respectively.
