From black technology to super engineering

Chapter 29 Girls Only Know Girls
Ye Ming has two things in one mind.

While writing the code, he talked to Ita in his consciousness, explaining the function of each command for "her".

Of course he knew, Ita couldn't understand.

But if you don't understand, it doesn't mean you can't remember!
As long as you pour it in from time to time, when "her" knowledge system reaches a certain level, then add association and extension, maybe it will have a miraculous effect.

The intelligent assistance produced by the system will not be able to defeat those AIs that run convolution and Bayesian.

#include
#include
void main ()
{
int a, b, c, d;//Integer declares a, b, c, d - what you say can be water...

float x1, x2;//Single-precision floating-point declaration x1, x-but there are not a few words, just skip it.

scanf("%d %d %d %d", &a, &b, &c, &d);
if(a==0) printf("x=%.2f", (float)(dc)/b);
else
{
float dr=b*b-4*a*c; c-=d;
if(dr>0)
{
x1=(-b-sqrt(dr))/(2*a);
x2=(-b+sqrt(dr))/(2*a);
printf(“x1=%.2f x2=%.2f\n“，x1，x2);
}
if(dr==0)
{
x1=(-b+sqrt(dr))/(2*a);
printf("x=%.2f\n", x1);
}
if(dr<0) printf("no answer\n");
}
}
When he finished writing the final code, Ye Ming felt his phone vibrate in his pocket.

He wanted to ignore it, but when he continued to work on the question, he inadvertently glanced at Qi and Mo who had just put down his phone.

After thinking about it, he took out his mobile phone and saw the message from her.

"Have you practiced against it before?"

Ye Ming smiled and returned quickly.

"No, but these are only difficult exercises."

Then, he turned his head slightly, and saw Qi and Mo pick up the phone again, and at the same time turned his head to look at himself, his eyes widened, and after a while, he smiled lightly, secretly gave him a thumbs up with his left hand under the table, and at the same time quickly replied.

"But this has stumped many people, let alone your speed is still so fast."

"There must be some bastards..."

……

The silent communication between the two of them on the mobile phone was completely watched by the girl sitting opposite them.

Subconsciously, she thought that the two were secretly discussing how to answer the questions.

And it was the message that the hairpin sister took the initiative to send.

Ha ha……

The girl smiled inwardly, glanced at her boyfriend who was putting all his energy into the code, and coughed lightly.

"The two don't need to use mobile phones to communicate."

Hearing the girl's words, Shen Ruhai raised his head.

Of course, he didn't put all his energy on the code. At least five minutes ago, he paid attention to the state of the paint and ink.

When Professor Chen asked him to lead the provincial "national team", he mentioned that there is a freshman student who is very good at C/C++.Although he is not from an Oier background, he is considered to be definitely talented.

As for Ye Ming, Professor Chen's original words were that this person is also very good, and it is due to this person that RC won RM, and the algorithm is particularly sharp.But when Shen Ruhai asked Professor Chen if Ye Ming was an oier, Professor Chen said no.

So Shen Ruhai had a little understanding in his mind, and this time he had a "foundation" about the two of them.

It's just that compared to Ye Ming, he pays more attention to paint and ink.

Following his girlfriend's words, he happened to see Qi and Mo look up, holding the phone with one hand.

"Sister." Qi Yumo said softly, without looking back, she just stretched out her finger from her shoulder and pointed behind her.

The meaning is obvious, pay attention to the impact.

The girl was slightly taken aback, subconsciously feeling a little annoyed.

Did I say impact?
"Is this question difficult? We need to communicate." The girl glanced at Qi Yumo with a smile, and then turned her head to look at her boyfriend.

Although she didn't understand ACM, or even programming, her boyfriend said that the question was simple, and he gave all the codes in just one class time...

It's only halfway through a class now, and the two of them started discussing...

She just hoped that these two would not hold her boyfriend back - even though they were recommended by Professor Chen.

But... everyone is a college student, who wouldn't fool the teacher?

People and papers are all looking for the shooter.

The two girls next door are both in graduate school, and they are looking for a gunman to do their graduation project, isn't there a lot of trouble?

Then...she saw that the girl with the pen hairpin was startled for a moment, and then smiled.

"Sister, the question is really not difficult, and we are really just chatting."

"Besides, in the ACM competition, the three-person team can only operate one computer, which is meant to be discussed, and it is also necessary to learn from each other's strengths for training and discussion."

"For example, he is already working on the sixth question."

Qi and Mo pointed at Ye Ming's notebook with a smile.

Even if she is not good at scheming, she can tell that this senior is a little bit... as if she is afraid that others will not know that her boyfriend is very powerful.

Even if her boyfriend is good, it's not that she is good.

She, a design student who read "Landscape Architecture Design Elements", came to point fingers at ACM, saying that foxes and tigers are polite.

Brainless is the correct expression.

ACM consists of three people. Although there is a captain, it only means who has more experience in the game, not who has the most powerful skills.

So she flattered the senior sister.

She believed that this senior could understand what she meant.

Sure enough... the senior was obviously displeased after being stunned for a moment, but soon the other party's attention was attracted by Shen Ruhai.

Because Shen Ruhai stood up in disbelief after hearing that Ye Ming had started the sixth question, and then turned to Ye Ming's side.

Question F: Deleting points into a forest, the difficulty factor is 4 stars (you don’t need to do it in freshman year).

Title: Given the root node root of a binary tree, each node on the tree has a different value.

If the node value is present in to_delete, we delete the node from the tree and end up with a forest (a collection of disjoint trees).

Returns every tree in the forest.You can organize your answers in any order.

A typical binary tree problem. Generally speaking, freshman students are not required to complete this question.

But Shen Ruhai did it, and it was done very quickly, and he remembered it deeply.

So he saw that Ye Ming was constantly writing correct codes.

……

Ye Ming left the keyboard with both hands.

He originally planned to wait for Paint and Ink.

On the one hand, he doesn't know how much time this senior spent last year to complete all the questions. On the other hand, if he leads too much paint and ink...

Right, at least demeanor is required.

This is not a real competition, just do a few random questions for fun.

To put it bluntly, questions of this difficulty are actually compared to hand speed, not skill.

But what the senior sister opposite... really made him a little upset.

Let's form a team, what are you doing here with a major who doesn't even teach hello world?

So he finished writing in front of Shen Ruhai.

"It's done." Ye Ming looked up at Shen Ruhai, with a faint smile on his face: "I hope I won't hold back the senior."

The expression on Shen Ruhai's face had already been managed, but his eyes... always had a trace of disbelief.

He calculated the time and it was exactly half an hour.

If you count the time spent chatting on the phone...

This means that Ye Ming wrote the answer directly without thinking at all.

Still the kind of standard answer!
So, Shen Ruhai felt that he still couldn't convince himself after all.

"Have you practiced the test list from last year?"

He looked at Ye Ming and asked as calmly as possible.
