Rebirth 07: Start adding points from elementary school students

Chapter 231 I am the One
Chen Fan had just glanced at the question when Li Yan heard a “Hmm?”

"It's not easy, don't worry, just understand the requirements of the question first."

"Do you have any ideas?"

"greedy?"

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

"Select the covering line segment and find the line segment with the farthest right endpoint among all the line segments with their left endpoints covered."

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

Chen Fan saw the engineering documents submitted by Li Yan and nodded.

"The key is the next step..."

“How to achieve greed.”

The soundproofing effect of the headphones was quite outstanding. In addition, Li Yan was fully focused on communicating with Chen Fan and had no energy to capture some extra sounds. So when he noticed that the surroundings seemed to be getting noisy, most people had already started the third stage of collaborative problem solving.

This made him feel a little anxious, as the third stage of questions had already advanced fifteen minutes.

At one point he wanted to find a complicated solution as a backup, but it was obvious that he was in a hurry.

Li Yan closed his eyes and adjusted himself for a few seconds, but his strong mind stabilized him.

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

The two of them pondered for a while and discussed a few ideas back and forth.

"Let the position covered by the current line segment be 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 Fan finished speaking and Li Yan understood what he meant. "Then analyze each line segment in the sequence one by one."

"That's what I mean. When analyzing a line segment, as long as now is greater than or equal to m, we can output the covered line segment and exit the program," Chen Fan said, quickly recording something in the document. "Some details are hard to get right now. Maybe we should hurry up and edit them first, and then see where we can optimize them."

"I have an idea." Li Yan's keyboard was almost smoking. "Everything is easy to talk about."

At this time, Chen Fan was actually a little overwhelmed. He knew how fast Li Yan could write code by hand. There were no reference materials for the actual test, nor were there various libraries for you to call upon.

Therefore, many people have strong programming skills in normal times, but when they get to the exam room, they have ideas but cannot put them into practice, so they can only take a roundabout way and use simple routines to solve the problem.

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

"Li Yan?"

“I’m working on it.”

"what can I do?"

"Think again, can it be further optimized?"

Chen Fan was about to say something when he saw another piece of code submitted to the draft box. However, it was not complete yet, so he could only take a look at it first.

Li Yan muttered to herself in the headphones:

As for what the formula is, Li Yan won’t tell you, because everyone is here to see him show off, not to do the questions.

I'm so tired from work and classes, isn't it a bit outrageous that I have to use my brain to solve problems while watching his performance?

He talked about it and moved his hands, and the moment the build was completed, he submitted the code to the draft box.

"This completes the analysis. After analyzing all line segments, now is less than m, which means that [0, m] cannot be covered. There is no solution and we exit."

Chen Fan compared the ideas he wrote in the document, wondering if there were any details in the question that could be optimized.

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

But from the perspective of performance, it is right to think more about the ideas.

Perhaps knowing Li Yan's style, or perhaps because he thought the value he provided in the cooperation question was too low, Chen Fan asked after testing it a few times: "Li Yan, only one and a half hours have passed..., and there are still three hours left before the end of the four and a half hours... Do you want to submit?"

"It was my words, I mentioned it."

"Okay, then..."

"But I'm just trying to show off, and I have to tell you that. According to the scoring criteria you mentioned, it would be more reasonable for us to spend three hours researching 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 we might as well shock everyone."

“I like this idea very much.”

Li Yan clicked Submit.

The ding-dong sound interrupted almost everyone's thoughts.

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

"The first group of the third stage completed the questions: E-11, E-12, New Taipei First High School, Chen Fan, Li Yan, took 32:04"

"Do these two junior high school students from New Taipei City No. 1 Middle School know that they will not receive extra points for their speed in solving problems?" Vice Chairman Zhang paid close attention to them - it was indeed hard not to pay attention to such performance.

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

"Let the backstage take a look." Vice Chairman Zhang adjusted the curled ends of his hair. "Tell me the results first, and then we'll see if it's worth reporting to Chairman Xu."

Once the topic is submitted, there is no room for modification.

There was no point for Li Yan and Chen Fan to sit here any longer, and they had to wear the stuffy noise-cancelling headphones, so Li Yan pressed the call button, and the staff of the examination room appeared next to him like teleportation.

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

“Do we need to exit early?”

You have to pretend to be cool, but you also have to be polite.

"You can leave the venue freely throughout the whole process, and you can leave in an orderly manner after confirming that the exam is over." Chen Fan wanted to ask whether he should confirm the information submission status, but Li Yan had already clicked to exit and pointed to the big screen.

The submission records are all above, and the official certification is as solid as a rock.

At the gate, Dong Chengliang waved his hand with a helpless smile, put his arm around a child's shoulder, and walked out of the examination room under the gaze of the teachers.

"You two... really made me stand out."

"Is it fun, teacher?" Li Yan asked.

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

He hadn't said anything else, but Li Yan understood.

"Everything depends on our grades, right?" Li Yan stretched her body. "If the grades are good enough, we can be the center of attention. If the grades are not good enough, we will just be clowns."

"That's not the way to say it... There's no need to carry such pressure. It's good enough for a junior high school student to be able to come and participate in the competition."

But Dong Chengliang's slightly troubled expression betrayed him. He was obviously worried that he might not even qualify for the junior high school group...

"No pressure." Li Yan waved her hand, "Because there is no option of 'bad grades'. Right, Chen Fan?"

Chen Fan said he didn't dare to speak.

"There's really nothing to worry about. I can guarantee that I got all the questions right. It's not like the program was not tested after it was written. If I can't get a 'good grade' even if I get all the questions right, then the organizing committee should consider whether the test paper is too easy."

"Okay, okay, let's save some good luck." Dong Chengliang laughed, "Now that we've left the examination room, let's get in the car and go back to the hotel, pack up and go back to New Taipei."

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

"Hey, Director Jin, what's going on? Yeah, 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 and wait, and he trotted back into the waiting room.

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

"Why can't we be invited back to give our acceptance speech?"

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

But Li Yan pointed his finger towards the examination hallway, and a person on Li Yan's attention list was walking out.

Deng Yudi is short, has a bowl-cut haircut, an overbite and a pair of gold-rimmed glasses... He can't really be described as good-looking, but he is very memorable.

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

"Li Yan, I've heard a lot about you. Today I see that you are indeed worthy of your reputation." Deng Yudi walked towards him, "This is Chen Fan, right? He is also very good. New Taipei First High School is still strong."

It was not the first time they met, they added each other on QQ the night before.

Chen Fan transformed into a boy with a fake smile.

"Brother Deng, why did you come out alone?" Li Yan subconsciously prepared to shake hands but braked in time.

Minors should not learn this.

"Uh... there was an oversight in the preparation for the third stage that my teammate was responsible for, and there was a bug in the back. The teacher is comforting her in the waiting room."

"It's okay. You submitted it, so the problem must have been fixed."

"Isn't this faster than you?"

……

Am I the culprit?
"Why are you waiting here?" Deng Yudi doesn't seem to be an introverted contestant, he's even a bit outgoing.

This doesn't seem like the typical computer genius temperament.

"We... are waiting for the teacher. Senior Brother Deng, are you waiting for the teacher too?"

"Well, why not chat about it? I'm very curious about you."

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

Two first-year junior high school students and a first-year senior high school student were sitting at the entrance of the gymnasium of Xin'an Middle School, chatting about the grand ambition of developing mobile phone systems and establishing the future smart mobile terminal ecosystem.

Until Deng Yudi’s teacher came out with a girl in tearful eyes - you, Deng Yudi, your partner is actually a girl?
They reluctantly ended the topic which had already progressed to "just build a mobile phone".

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

“You can indeed understand recruiting talents to work on projects as negotiating business.”

"What about Zheng Da and Rao Feng?"

"Let's wait for the results. I don't really expect to complete any big project by gathering some outstanding high school students who still have academic work to do. But at least in the early stages, I need a team."

Chen Fan swallowed back the words "Why do you feel like these two are not worthy of your attention?" and changed the subject:
"Where did Teacher Dong go?"

"You mean what you say..." Li Yan pointed to the examination room corridor again.

The person who came out was Dong Chengliang, who was laughing so hard that his eyes could not be seen.

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

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

Dong Chengliang happily took his two children and strode out of the gymnasium with his head held high.

"Director Jin just came to me and told me that they have reviewed the documents you submitted in advance. The specific scores have not been given yet, but at present, you two have reached the 'correct' step." Dong Chengliang sat in the co-pilot seat and lowered the seat back. "In other words, you can definitely represent Linjiang Junior High School students and participate in the national competition!"

Chen Fan let out a long sigh, his smile warm and innocent.

Li Yan on the other side had no reaction.
