Chapter 231 There is me among others


Chapter 231 There is me outside the world

Chen Fan just glanced at the question, and Li Yan’s headset said "Huh?"

"It’s not easy, don’t worry, just wait Know the requirements first.”

“Do you have an idea?”

“Greedy?”

"Well... first sort all the line segments in ascending order according to the left endpoint as the first keyword and the right endpoint as the second keyword..."

"Select the covered line segment and find the right end of all line segments with the left endpoint covered. Click on the farthest line segment."

"Oh...you're done, right?"

Chen Fan saw the project document submitted by Li Yan and nodded.

“The key is the next step of thinking...”

"How to achieve greed."

The sound isolation effect of the headphones is quite outstanding, and Li Yan was fully focused on communicating with Chen Fan and had no energy to capture some additional sounds, so when he noticed that the surroundings seemed to be noisy, Most people have begun the third stage of collaborative problem-solving.

This made him a little nervous. The questions in the third stage had already advanced for fifteen minutes.

At one point, he wanted to find a cumbersome solution to save the day, but it was obvious that he was anxious.

Li Yan closed his eyes and adjusted for a few seconds before his powerful mind stabilized him.

There is still a long time, and a sufficiently accurate, complete and efficient answer is what they need.

The two of them thought about it for a while, discussing a few ideas back and forth.

“Suppose the position covered by the current line segment is now; among all the line segments whose left endpoints are covered, the farthest position that can be covered is l, and this line segment is k...”

Chen Li Yan understood what Fan was saying halfway, "Then analyze each line segment in the sequence in turn."

"That's what it means. During the process of analyzing line segments, as long as now is greater than or equal to m, you can output the covered line segments and exit the program. ," Chen Fan said, quickly recording something in the document, "There are some details that are difficult to correct right now. Maybe we should compile them first and then see where they can be optimized."

"I have an idea." The keyboard on Li Yan's side started to smoke, "It's easy to say anything."

At this time, Chen Fan was actually a little at a loss. He knew that Li Yan could rub the code with his hands very quickly. What an exaggeration. There is no reference material for the actual computer exam, and there are no various libraries for you to call.

So many people usually have strong programming skills, but when they get to the examination room, they have no ideas and are difficult to implement. They can only save the country through curves and use simple routines to solve the problems.

This shows how valuable Li Yan’s skills are in today’s examination room.

“Li Yan?”

"We're working on it."

"What can I do?"

"Think about it again and see if it can be further optimized."

Chen Fan was about to say something when he saw the draft Another piece of code was submitted in the box, but it is not complete, so I can only take a look at it first.

Li Yan’s soliloquy in the headphones:

Li Yan won't tell you what the formula is, because everyone comes to see him show off and not do the questions.

After being so tired from work and class, it’s outrageous to have to use your brain to solve problems while watching him perform, isn’t it?

As he spoke and moved his hands, he submitted the code to the draft box as soon as the construction was completed.

"In this way, the analysis can be completed. After analyzing all the line segments, now is less than m, which means that [0, m] cannot be covered and exits without a solution."

Chen Fan compared what he wrote in the document ideas, wondering whether there are any details that can be optimized in the question.

Li Yan hesitated to speak. If this was a single question, he would have submitted it directly.

But from a performance perspective, it’s right to think more about your ideas.

Perhaps because he knew Li Yan's style, or perhaps because he thought that the value he provided in the cooperation questions was too low, Chen Fan tested it several times and asked: "Li Yan, only one and a half hours have passed in total. ..., there are still three hours until the end of the four and a half hours...Do you want to submit?"

"It's my word, I mentioned it"

"Okay, then... ”

"But I am just trying to show off, and I must let you know this. According to the scoring criteria you mentioned, a more reasonable approach for us is to spend three hours to continue studying other ideas, or to continue working hard to reduce one calculation."

"Pretend." Chen Fan laughed, "We can't participate in the main competition anyway, so why not shock everyone more."

"I like this idea very much."

Li Yan clicked submit.

This ding-dong almost interrupted everyone’s thoughts.

More than a hundred pairs of eyes looked at the big screen.

"The first set of questions in the third stage was completed: E-11, E-12, New Taipei No. 1 Middle School, Chen Fan and Li Yan, in 32:04"

"New Taipei No. 1 Middle School these two A junior high school student, did you know that no points are awarded for solving problems? "Vice Chairman Zhang is very concerned about them - it's really hard not to pay attention to this kind of performance.

"Indeed, they should choose to further optimize." Director Jin took a deep breath and said, "Since everything has been submitted, why not take a look at the backend?"

"Let the backend take a look." Deputy Zhang The chairman straightened the ends of his raised hair, "If you have any results, tell me first, and then we will see if it's worth reporting to Chairman Xu."

Once a question is submitted, there is no room for revision.

It makes no sense for Li Yan and Chen Fan to sit here anymore. They have to wear stuffy noise-canceling headphones, so Li Yan pressed the call button, and the staff in the examination room arrived as if they teleported. next to him.

From the moment Li Yan submitted the answer, the staff was ready to come.

“Do we need to leave early?”

You have to pretend to be cool, and you have to be polite.

"You can leave freely throughout the entire process. You can leave in an orderly manner after confirming that the exam is over." Chen Fan also wanted to ask if he wanted to confirm the information submission status. Li Yan had already clicked Exit and pointed at the big screen. .

The submission records are all up there, and the official certification is as stable as a dog.

Dong Chengliang smiled helplessly at the gate, waved his hand, put his arm around a child's shoulder, and walked out of the examination room as the teachers watched.

“You two... made me shine.”

"Are you happy, teacher?" Li Yan asked.

Dong Chengliang shook his head and smiled bitterly, "I was ridiculed by the other team leaders."

He still had something to say, but Li Yan understood it.

“Everything depends on our grades, right.” Li Yan stretched her body, “If our grades are good enough, we will be the ones to steal the show this time. If our grades are not good, we will be like clowns.”

"That can't be said... There is no need to carry such pressure. It's good for junior high schools to come and compete."

But Dong Chengliang's slightly tangled expression betrayed him. He was obviously worried that if he didn't even qualify for the junior high school group...

"There is no pressure." Li Yan waved his hand, "Because there are no results. Not a good option, right Chen Fan?"

Chen Fan said he didn't dare to speak.

“There’s really nothing to worry about. I can guarantee that all my questions are correct, and it’s not like there’s no test after writing the program. If you can’t get a ‘good grade’ even if you’re all correct, it’s the organizing committee’s fault. Consider whether the difficulty of the test paper is too easy. "

"Okay, let's save some character." Dong Chengliang laughed, "Now that the examination room is out, prepare to get in the car and go back to the hotel to pack up. Back to New Taipei.”

As soon as he finished speaking, his cell phone rang. As soon as he saw the call information clearly, Teacher Dong immediately frowned.

"Hey, Director Jin, what's the matter? Yes, okay, I'll go over now."

Then he hurriedly asked Li Yan and Chen Fan to go back to the chairs in the aisle of the gymnasium to wait, while he I jogged and entered the examination waiting room again.

"What's wrong? Are we violating the rules?" Chen Fan sat down carefully.

“Why can’t we be invited back to give an acceptance speech?”

"You...I mean, if we leave so early, will it have a bad impact? Director Jin criticized Teacher Dong?"

But I saw Li Yan pointing her finger at the examination room passage. A person on Li Yan's attention list came out.

Short, with a pot head, a big head, and a pair of gold-rimmed glasses... Deng Yudi is really not good-looking but very memorable.

"Look, although speed doesn't count, everyone is still competing. If I were Director Jin, I would be happy to see this kind of scene." Li Yan said with a smile.

"Li Yan, I have heard so many legends about you. Today I saw that your reputation is well-deserved." Deng Yudi walked straight up, "Is this Chen Fan? He is also very powerful. New Taipei No. 1 Middle School is still strong. .”

This was not the first time they met, QQ was also added the night before.

Chen Fan transformed into a boy with a fake smile.

"Senior Brother Deng, why did you come out alone?" Li Yan subconsciously prepared to shake hands and stopped the car in time.

Minors should not learn this trick.

"Uh... in the third stage, my teammate was responsible for an omission in the front part, and there was a bug in the back. The teacher was comforting her in the waiting room."

"It's okay. You submitted everything. You must have corrected the problem."

"Isn't this faster than you?"

......

I am the culprit. Already?

“Why are you waiting here?” Deng Yudi doesn’t seem to be an introverted player, and is even a bit familiar.

He doesn't quite have the temperament of a typical computer genius.

"We...are waiting for the teacher. Does Senior Brother Deng also want to wait for the teacher?"

"Well, why don't we chat, I'm very curious about you."

Just be curious, Chen Fan clearly saw the smile on the corner of Li Yan's mouth.

Two first-year junior high school students and a first-year high school student were sitting at the entrance of the Xinan Middle School gymnasium, chatting about the grand project of building a mobile phone system and establishing a future smart mobile terminal ecosystem.

Until Deng Yudi’s teacher came out with the girl with tearful eyes - you Deng Yudi, your partner is actually a girl?

They reluctantly ended the topic that had advanced to "build a mobile phone directly".

"Why do you feel like you are discussing business?" Chen Fan didn't know how to interrupt.

“Recruiting talents to do projects can indeed be understood as talking about business.”

“What about Zheng Da and Rao Feng?”

"Let's wait for the results. I don't really expect that by gathering some outstanding middle school students who are still studying, we can complete any big project. But at least in the early stage, I need a team."

Chen Fan said " Why do you feel like these two can't get into your eyes?" He swallowed it back and changed the subject:

"Where have you been, Teacher Dong?"

"You are so casual about what you say... ..." Li Yan pointed to the examination room passage again.

The person who came out was Dong Chengliang, who was smiling so hard that he couldn't see his eyes.

"Is there any good news?" Chen Fan finally showed a positive expression.

"Of course, let's go, let's get back to the car first."

Dong Chengliang happily pulled the two children and left the gym with his head held high.

"Director Jin just came to me and said that they had read the documents you submitted in advance, and the specific points have not been given yet, but at present, you have both achieved the 'correct' step." Dong Chengliang sat In the passenger seat, the seat back was lowered, "That means you can definitely represent Linjiang Junior High School students in the national competition!"

Chen Fan took a deep breath and smiled warmly and innocently.

Li Yan on the other side showed no reaction.
