The main function of the first and second floors of the library is to borrow and read books.
So on the third level, the main function is self-study.
For a long time, this has been a place where senior students prepare for the postgraduate entrance exams.
In addition to tables and chairs used for studying, there are also several beanbags set up around the area so that you can take a nap after working hard all night.
However...the objective law of the development of things is to deviate from the original intention.
The third floor is certainly a holy place for seniors to prepare for exams, but it is also a place for lovers to fall in love.
Those beanbags are large enough for couples to relax and cuddle up after a stressful day of studying.
However, it was only 8 o'clock at this time, and the seniors and seniors were still restrained. Everyone remained quiet, and even when discussing issues, they were quite restrained.
…
A pair of boys and girls sat at the desk not far from the door. The boy had a notebook in front of him, and the girl had a book "Elements of Landscape Architecture Design" in front of her.
It's just that the girl's mind is obviously not on the book. She sometimes looks back at some couples who are quietly "spreading dog food", and sometimes she secretly glances at the boy next to her.
The boy's expression is serious and serious.
In the eyes of girls, this is what a boy with high IQ should look like.
——My boyfriend participated in the Information Olympiad in high school (the Youth Olympiad in Informatics is abbreviated as OI, and participants are generally called oier.). Due to various reasons, he came to the provincial capital and continued to participate in ACM during his freshman year... ...However, due to the lack of performance from my teammates, I ended up in the regional competition.
To put it in my boyfriend's words, he really can't take her with him.
Fortunately, gold always shines.
Although my boyfriend failed to fulfill his long-cherished wish at ACM, he was recognized in Teacher Chen’s research group.
As a sophomore, he was at ease in a research group full of masters and Ph.D. students.
What is strength?
This is strength.
What is a genius?
This is genius.
Today, she came with her boyfriend. On the one hand, it was because her boyfriend was busy with scientific research and they didn't have much time to see each other. On the other hand, she also has some extra thoughts...
It is said that there is a software engineering school girl.
Although she is very confident in herself, a creature like a school girl... right?
"Ruhai, it's almost a quarter past eight. Why aren't you here yet?"
The girl touched Shen Ruhai and asked with a smile.
Without blinking, Shen Ruhai moved the phone towards her: "Ask me."
The girl smiled happily and picked up her phone, quickly unlocked it with the password, then opened WeChat and clicked into the group group.
She frowned slightly, then her expression became serious, and she typed a question.
"Where are you two? Can you have a sense of time?"
It took less than five seconds for the message to be sent.
The school girl named Qi Yumo responded with a message.
"Sorry, senior, I'm already climbing the stairs." At the end, he replied with a smiley face.
The girl turned her head and glanced at Shen Ruhai. After thinking about it, she felt that it was right to say nothing back.
So she turned off her phone and looked at the door seriously.
A minute later, a pair of young boys and girls appeared at the same time.
The man has a calm expression on his face, while the woman has a slight smile. Compared to her face, what people notice is that she seems to have a gel pen stuck in her head.
Put a pen in your head?
The girl snorted slightly in her heart, and then she touched her boyfriend.
Then she noticed that her boyfriend's eyes lit up without leaving any trace when he saw the girl with a hairpin.
…
"Hello, senior." Qi and Mo greeted the senior first, and then looked at the girls next to the senior with some confusion.
"Well, here we are." Shen Ruhai nodded to Qi Qi, Mo and Ye Ming: "We won't talk nonsense. Here are six questions, which are the real questions from last year's ACM campus qualifiers. Although it is relatively simple, within the stipulated time, there are only Less than 30% of people are completely correct. And even if they are all correct, it doesn’t mean anything, because the ACM competition principle is to be both fast and accurate.”
With that said, Shen Ruhai pushed over two printed A4 papers.
"Who is this?"
"Oh, your senior sister from the Design Institute, she is not participating, she just came to have a look." Shen Ruhai smiled and nodded, then looked at Ye Ming: "Ye Ming, right? I heard that you are not from the computer department?"
"Well, I'm in electronic information engineering."
"As for ACM, we usually use C/C++, are you okay?"
Ye Ming nodded calmly: "It's okay, so is Python."
"I generally don't use Python. Over the years, I have basically used Python on most numbers, or JAVA."
After saying that, Shen Ruhai glanced at the time: "Okay, let's get started."
Ye Ming, Qi Yumo looked at each other: "Where's the senior?"
Shen Ruhai smiled reservedly, and before he could say anything, the girl next to him laughed: "Your senior was the number one player in the school preliminaries last year, and he was still an oier - didn't Boss Chen tell you?"
The two looked at each other again.
Qi Yumo smiled slightly: "Then please give me some advice, senior."
Ye Ming also smiled and nodded, then opened his notebook.
At the same time, look at the A4 paper.

"ACM Programming Competition Selection Preliminary Round"
Time: 150 minutes Number of questions: 6 questions
Note: There is no limit to the problem-solving algorithm. As long as the input can be done in a standard format and the correct result can be obtained through the program, this question will receive full marks. If the question cannot be completed completely, please explain the ideas clearly.
A: Alphabetical order. Difficulty factor 1 star
Question meaning: There are 10 English letters (including upper and lower case letters). Use a computer to achieve the following functions. Sort these 10 letters in the order of English letters A, B, C..., Z, a, b, c,..., z and output them. Note: Lowercase letters should come after uppercase letters.
Input: Enter any 10 English letters. JIEBACDFHG/jiebacdfhg/JiEbacdFHG
Output: The sequence of these 10 letters sorted. JiEbacdFHG/abcdefghij/EFGHJabcdi
Looking at the title, Ye Ming secretly shook his head.
Is it so simple to fool primary school students?
#include
void main()
…
cout<

After successfully writing the answer code, Ye Ming continued to look at the next question.
B: Numbering arrangement, difficulty coefficient 2 stars.
n people form a circle and number them from 1 to n in clockwise order...
Ye Ming just thought for a moment and wrote down the code again - no more than thirty lines of code.
…
As Ye Ming continued reading, his hands never stopped, as if... he was typing while looking at the text.
Or maybe chatting with someone.
Soon, he completed question D and came to question E to solve the equation.
Question meaning: An equation of the form ax 2 +bx+c=d. Among them, a, c, d are all integers, and b is a positive integer. Please use a computer to find the corresponding value of x (only consider real roots).
Ye Ming stopped at this time.
It's not that he can't write the code to solve equations, but that he just reviewed the junior high school knowledge while teaching Ita at noon today.
This quadratic equation looks particularly familiar.
How about letting Eta try it?
"Ita."
"exist."
"Want to learn programming?"
"What is programming?"
“The use of a specific computer language to instruct a computer to perform a specified task.”
"Like the mathematical language you taught me?"
Ye Ming was startled when he heard Eta's answer.
He's stupid.
Eta itself is an AI, and she lets the AI learn programming... Where is this matryoshka doll?
As expected, he randomly assigned several values to abcd in question E and asked what the value of X was. Ita answered immediately.
So he slapped his forehead and shook his head with a self-deprecating smile.
His movement also attracted the attention of Qi and Mo beside him.
She just finished the third question, which took a total of fifteen minutes so far.
Then she saw Ye Ming starting the code for the fifth question.
She was suddenly startled.
So fast?
