If 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 place so that you can take a nap after working hard all night.
However...the objective law of the development of things is that it deviates 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 together after a stressful day of study.
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 are sitting at a desk not far from the door. The boy has a notebook in front of him, and the girl has 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 (Youth Olympiad in Informatics, referred to 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 gained recognition in Mr. Chen’s research group.
As a sophomore, he was at ease in a research group that was full of masters and Ph.D. students.
What is strength?
This is strength.
What is 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 had 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 haven't you come yet?"
The girl touched Shen Ruhai and asked with a smile.
Shen Ruhai didn't blink and moved the phone towards her: "Ask me."
The girl laughed 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 replied with a message.
"Sorry, senior, I'm already climbing the stairs." At the end, he replied with a smiling emoticon.
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's face has a calm expression, 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 said hello to the senior first, and then looked at the girls next to the senior with some confusion.
"Well, here we come." 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 school qualifiers. Although it is relatively simple, within the specified time, 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. Is that okay with you?"
Ye Ming nodded calmly: "It's okay, so is Python."
"I generally don't use Python. Over the years, I have basically used Python for large 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?"
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, he looked at the A4 paper, and then he was startled.
At first glance, except for a binary tree...it seems to be all basic knowledge. In order to give students confidence, schools have made it as simple as this?
Time: 150 minutes Number of questions: 6 questions
Note: There is no limit to the algorithm for solving the problem. As long as it can be input according to the standard format and the correct result can be obtained through the program, the question will get full marks. If the question cannot be run completely, please explain the idea clearly.
A: Alphabetical order. Difficulty factor 1 star
Question meaning: There are 10 English letters (including upper and lower case). 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. Note: lowercase letters should come after uppercase letters.
Input: Enter any 10 English letters.JIEBACDFHG/jiebacdfhg/JiEbacdFHG
This chapter is not over, please click on the next page to continue reading! Output: These 10 alphabetical sequences.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 down the answer code, Ye Ming continued to look at the next question.
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 moved on to question E to solve the equation.
Question meaning: An equation of the form ax 2 bx c=d. Where a, c, d are all integers, and b is a positive integer. Please use a computer to find the corresponding value of x (only real roots are considered).
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 is 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, shook his head and smiled at himself.
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 that Ye Ming started the code for the fifth question.
