Genius Girlfriend

Time passed by, and Cai's finger hovered over the computer keyboard.

Lao Cai is a careful person. When he writes programs, he pursues excellence. He turned his head to discuss with Xiaoliang how to improve the efficiency of the program. Lin Zhixia couldn't find the time to interrupt, so she could only sit in her seat, quietly listening to the conversation between Lao Cai and Xiao Liang in full swing.

Lao Cai felt that he had pushed Lin Zhixia out of the team. He was a little guilty. He told a joke to liven up the atmosphere, and asked Lin Zhixia to check the code for him.

Lin Zhixia glanced and confirmed that there was no problem with Lao Cai's procedure.

Before this, Lin Zhixia once pointed out that Lao Cai's "binary string should not be shifted two bits to the left". However, it now appears that Cai's thinking is correct. Lin Zhixia apologized to him: "Sorry, I made a mistake just now. I didn't expect you to write this way. Your method of solving the problem is completely different from mine."

Lao Cai adjusted the position of the seat. While submitting the code, he said to Lin Zhixia: "Hurry up, let's study the sixth question. The sixth question is algebraic geometry..."

Lao Cai didn't finish a word, Xiao Liang's finger tapped the table: "The fifth question is wrong."

Lao Cai and Lin Zhixia raised their heads together, and looked at the computer screen together.

IHSPC is a cruel and rigorous competition. The scores of each team are updated in real time and are open and transparent. Contestants upload the code of a certain question, and the background program will immediately determine the score.

Right and wrong, scoring and deduction, all in one thought, but also in an instant.

Lao Cai felt the tremendous pressure. He held his breath, his voice hoarse: "We wrote the fifth question incorrectly?"

A big mistake was made in the fifth question, with 7 points deducted. The overall ranking of Provincial No. 1 dropped from sixth in the audience to 17th in the audience.

Up to now, the Russian team and the South Korean team are far ahead, followed by several participating teams from China. The Provincial No. 1 Middle School does not have any advantage, Lin Zhixia's heartstrings are tense, and he hurriedly checked the backstage feedback. She said: "You use a binary string to represent the set of the fifth question, shifting two to the left represents multiplying by 4. But you missed one case... I was wrong too, I didn't read every line of your code carefully."

Lao Cai frowned tightly, his face still dark. He held the mouse, refreshed the page, and the ranking of the game was updated again-the provincial No. 1 was reduced to 19th.

Lin Zhixia is the first in grade every time she takes an exam. She has never seen a "19th place" score. She was a little confused. Lao Cai is still revising the fifth question. Xiao Liang calmed down and said, "Lao Cai, don't worry, there is still a chance."

Lao Cai submitted the fifth question for the second time and was judged as "Error" again.

This "Error" means "error". The Provincial No. 1 High School was deducted 4 points, and the overall ranking dropped continuously.

"It's terrible." Old Cai said with emotion.

Lin Zhixia blocked Lao Cai's hand and directly grabbed the keyboard. She added a new variable based on Lao Cai's program. She clicked the left mouse button and pressed the green confirm button. However, she did not turn the tide. "Error" appeared repeatedly, and the ranking of "No. 1 Provincial High School" sank to 43rd.

Xiao Liang criticized without mercy: "Lin Zhixia, you made it too fast, we didn't see your writing clearly."

At this time, Lin Zhixia took out the test questions and re-read the fifth question. She said to her teammates: "I see, we all remembered this question incorrectly. Two weeks ago, when the teacher took us to train, he gave us a question. That question is 100% of the fifth question. The similarity is 80, but the qualifications are completely different..."

Lin Zhixia hasn't finished speaking yet, Xiao Liang and Lao Cai are already working together to make changes.

They were unanimously inspired by the gambler mentality.

The harder they lose on the fifth question, the more they have to try until the fifth question is answered correctly.

Lin Zhixia pointed to the screen and suggested: "Delete this function, it is redundant code."

The so-called "redundant code" refers to code that does not need to exist.

Xiao Liang's fingers flicked on the keyboard, but he ignored Lin Zhixia. Xiao Liang and Lao Cai lowered their heads and whispered for a while, exchanged opinions seriously, and submitted the answer to the fifth question again—this time, they finally succeeded.

The huge competition venue is full of conversations in various languages.

The opposite Russian team is talking and laughing, and they are currently ranked first in the game. The Estonian team next door looked solemn, and the three teammates were drawing pictures while discussing the sixth question.

Outside the wide floor-to-ceiling windows, there was a damp mist. The windows were stained with hazy drops of water, and the sky became paler and paler. The buildings in the distance stand in rows, reflected in the dark background, like an oil painting with profound artistic conception.

Lin Zhixia was distracted.

Lin Zhixia only owned the first computer this year, while Lao Cai and Xiao Liang learned programming since childhood. Xiao Liang's father and mother were both programmers in a computer company in the provincial capital. It can be said that they came from a "programmer family". Perhaps Lin Zhixia should adjust her state and work hard to do support work.

After much deliberation, Lin Zhixia nodded. She dragged the chair and approached Lao Cai.

Lao Cai opened the main page of this competition. He saw that the Provincial No. 1 Middle School was ranked 49th, and the teams behind were still on the upward trend. According to this situation, they would continue to develop, not to mention the gold medal, the bronze medal was hopeless.

Lin Zhixia asked in confusion: "Why are we getting closer and behind?"

Lao Cai said: "Russia and the United States have sent more than 20 teams. Look at the high schools in the United States, they are all in the front, and even the British schools have surpassed us..."

Lin Zhixia quickly said: "I know how to do the fourth question. As long as we answer the fourth question correctly, the score in Provincial No. 1 High School will be up!"

"How to do the fourth question?" Lao Cai asked her back, "Or the method just now?"

Lin Zhixia is very sure: "Yes."

Lao Cai pushed up the glasses on the bridge of his nose. He still thinks Lin Zhixia's approach is problematic, just like he wrote the fifth question incorrectly. He felt that Lin Zhixia's perception of the fourth question was wrong. He suggested that Lin Zhixia first create a set of data on draft paper, and then substitute this set of data into her program to check whether her method is successful.

"I have checked it in my own mind." Lin Zhixia said honestly.

Lao Cai said, "You write it down and write a few more pages. I will ask you step by step. You just submitted the fifth question and didn't let me and Xiao Liang check it. You made a mistake and the team lost four points."

Lin Zhixia reached out and hit the keyboard: "In the beginning, I thought that the fifth question was a routine problem that we had encountered before... You and I made the same mistake. This is the principle of "three people become a tiger"-three Individuals have confirmed the same thing, whether it is true or false, their first reaction is to follow the trend."

Lao Cai stroked the keyboard with his right hand. He was thinking about the sixth question. And Lin Zhixia's words made him inexplicably irritable. He took off his glasses, put them on the table, raised his palm, and rubbed his face abruptly.

Lin Zhixia's rhetoric is set, which upsets Lao Cai.

On the IHSPC, the most taboo thing is that teammates blame each other-Lao Cai has received more than two years of training, and he and Xiao Liang are very aware of this rule. However, Lin Zhixia didn't seem to understand, or she just felt it didn't matter to tell the facts.

Lao Cai held his forehead: "Lin Zhixia, how old are you this year?"

Lin Zhixia moved an inch back: "I am twelve years old this year... I am thirteen years old, and will soon be fourteen years old."

Lao Cai pointed to himself, then pointed to Xiao Liang: "We are several years older than you."

"Our souls are equal," Lin Zhixia muttered to herself, "No matter if I am twelve or ninety-two, I will treat you with the same attitude."

Xiao Liang "tsk": "You are twelve years old this year, not ninety-two years old..."

Lin Zhixia remembered her business: "Time is so tight, can I use the computer to write the fourth question?"

Lao Cai couldn’t bear it, and broke out: “You write down the steps, can’t you? You will deduct points if you answer wrongly. You are a human being, not a god, you make a mistake, and your teammates will clean up the mess for you. Up?"

Lin Zhixia slowed down for two seconds and confronted him tit-for-tat: "Can you not attack my age? I do make mistakes. Everyone makes mistakes. As long as we correct them, that experience will be meaningful."

Lao Cai collapsed and said, "Don't talk about chicken soup with me."

Lin Zhixia patiently explained: "I can write down the steps of the fourth question, but the fourth question is a recursive exponential function. I will use number theory to write it, and then apply Fermat's theorem. I see that there is no People are using the keyboard, so I suggested that I write the program, and then I use the code to explain in detail to you. This will be clearer to you than what I wrote by hand. I can also write the program code on paper , And then copy it into the compiler... just this way, you may not be able to check every step of mine, because the code is destined to be concise and jumpy, you can not debug with the naked eye."

"Debug" is a programming term that refers to "resolving program faults."

Lao Cai did not answer. His eyes focused on the display.

The ranking of Provincial No. 1 is still falling. There is also an African national team, which has been promoted to the top of the provincial one.

The African team?

In Lao Cai's impression, Africa is an underdeveloped region. He has watched a documentary of a city in Africa-the outskirts of that city are the African grasslands. Lions, antelopes and zebras happily ran on the outskirts of the city, which shocked him greatly.

He was surpassed by the African team.

Lao Cai is not even sure whether the students of the African team are safe in their daily lives, will they be chased by lions, teased by leopards, and threatened by elephants.

And he, who was trained in a delicious and delicious way in Provincial No. 1 Middle School, and enjoyed the hospitality of the canteen chef, is not even comparable to a team from Africa.

Lao Cai's chest was filled with suffocation, which blocked his lungs. He stated slowly: "You won the gold medal in the Romanian Masters and you came to participate in the information competition. The teacher had to put you in our group and squeezed out our original teammates. Me and the person who was squeezed out , Is a good friend of five years in middle school. The teachers insist that you are smart, you are strong, you are capable, and you have talent. Okay, well, I agree with you to join the team. You still deducted four points for us, this is you Strength?"

Lin Zhixia sat in a chair and moved a distance back. She didn't want to listen to Lao Cai anymore.

Especially, when Lao Cai said that he and the squeezed player were good friends from five years in middle school, Lin Zhixia suddenly thought of Jiang Yubai. If anyone squeezed out Jiang Yubai's position, Lin Zhixia would be very angry.

However, the information coach did not tell Lin Zhixia that Lao Cai, Xiao Liang and that person are good friends and teammates who have been training together all the year round.

The coach only said: Lao Cai, Xiao Liang, Lin Zhixia, the three of you are the most suitable team. Lin Zhixia, your personality and mentality are very good, and you also won the gold medal in mathematics in the international competition. Teaming up with Lao Cai Xiaoliang, you will definitely win the IHSPC trophy!

Lin Zhixia's mood is very depressed.

Lao Cai is still accusing her: "The first time I made a mistake in the fifth question, you said that I had missed a situation, pointed me to the crooked road, and lost seven points. After these few toss, the African team can overtake us ..."

"I have already admitted that I was wrong." Lin Zhixia looked at the invigilator who was getting closer, and consciously lowered her voice. "This is an accident in itself. We should share the risks and the consequences equally, because we are a team. ."

IHSPC stipulates that contestants can discuss in a low voice, but not loudly.

Lao Cai's voice was slightly louder, which affected the New Zealand players sitting behind him.

New Zealand players give feedback to the invigilator. The teacher verbally warned the team of the Provincial No. 1 Middle School: "Excuseme, could you please lower eryour voice?"

Lin Zhixia hurriedly apologized: "Sorry, myteammatesandI..."

Before Lin Zhixia finished speaking, the teacher stopped her words: "Thatisallright."

After speaking, the teacher left.

Xiao Liang shrank in the corner and did not hear the English question and answer of the invigilator. He asked Lin Zhixia: "What happened?"

Lin Zhixia relayed: "The teacher asked us to be quieter. I said I'm sorry, but the teacher's answer is okay."

Sudden situations occurred one after another, and Lin Zhixia and her teammates were a little absent-minded. Lin Zhixia still wants to write the fourth question, Xiao Liang Yuanchang said: "Forget it, let's do the sixth and seventh questions first."

Lao Cai is writing the sixth question on the computer. He compiled it several times. Xiaoliang and Lin Zhixia helped him establish a set of input and output data standards.

The time on the field fled so fast, the ranking of Provincial No. 1 was raised three times and dropped four times. There was a thin layer of sweat behind Lao Cai. Although the answer to the sixth question was correct, his method took a long time and the final score was low. He tried a different method, and as a result, the sixth question became "Error". Not only did he not earn points, he also caused a little loss.

He quickly stabilized his emotions and assigned the remaining questions to his teammates.

Lin Zhixia supported her cheek with one hand and began to read the tenth question-the tenth question was the finale of the competition, involving complex points geometry. Integral geometry was originally one of Lin Zhixia's best areas, but when she transformed mathematical thinking into programming language, the Russian team had already completed the tenth question.

The Russian team sat directly opposite Lin Zhixia.

The three Russian boys all smiled and silently celebrated the victory. They are more than a dozen points higher than the second place Zhejiang team, and it seems that they are destined to win the gold medal in this game.

The Zhejiang team is playing hard against a South Korean team. Whenever the South Korean team surpasses the Zhejiang team by a few points, the Zhejiang team will catch up frantically. As the game progressed, the Zhejiang team even bit the Russian team, only three points lower than Russia.

Lin Zhixia looked at the computer screen and quietly cheered for her compatriots: "Come on Zhejiang, come on Zhejiang, hurry up and surpass Russia."

Lao Cai's mother is from Zhejiang. He regretted why he was not in the Zhejiang team.

Lao Cai refreshed the page in vain, and the Zhejiang team's score often changed. Lao Cai simply turned off the page. He continued to discuss the topic with his teammates, but new differences occurred. This time, Lao Cai and Lin Zhixia agreed, but Xiao Liang had different views from them. Xiao Liang also said: "If A Zhou is here, A Zhou will be on my side."

This "A Zhou" is the teammate who was unfortunately screened out.

The atmosphere in the team is even lower.

By the end of the competition, the Provincial No. 1 Chinese Communist Party had answered six questions correctly and reported many errors. Their final ranking was 24th, and they won a participation award.

At first, Lin Zhixia didn't feel sad. Almost at the moment when the contradiction broke out, she had predicted the ending.

However, on the way back, Lao Cai and Xiao Liang assumed all responsibilities in front of the coach. They said that the reason for the big mistakes in this game was because of their poor condition on the field. Neither of them mentioned Lin Zhixia's mistake on the fifth question.

Lin Zhixia asked Lao Cai privately, but Lao Cai said, first, he and Xiao Liang did not stabilize their emotions, and second, when he and A Zhou were teammates before, he was used to helping A Zhou to relieve the siege.

When they returned to the Provincial No. 1 Middle School, the two coaches of the information sciences looked sad. It turns out that the final ranking of IHSPC this time is the worst result in the history of the Provincial No. 1 Middle School.

Last year, the Provincial No. 1 Middle School won the bronze medal.

This time, there was only one trivial participation award in the Provincial One.

Lin Zhixia has an afterthought. She left the high school in a daze, and walked back to the classroom of the third (seventeen) class of junior high school. Her fiasco experience in Moscow, Russia, has long been passed back to the third grade. The classmates in Class 17 saw her entering the door, and no one said anything, and everyone didn't know how to comfort her.

Lin Zhixia sat back in her seat quietly.

Jiang Yubai turned his head and looked at her: "Lin Zhixia?"

Lin Zhixia's voice was extremely small. She said to herself: "Don't call me, let me think about it alone, what is the problem? Is my attitude not serious enough... But I tried my best, I didn't dare to fight, the voice was too loud. The disqualification of the competition will also affect the next contestants in our school... I don’t know what to do. They don’t believe the method I said. I don’t believe in their method either. Later, I will change It has to be more negative and low... During training, everyone gets along well, but when it comes to the game, my mentality has also changed..."

"Lin Zhixia," Jiang Yubai interrupted her, "Everyone will be affected by the environment. Don't blame yourself."

Lin Zhixia's eyes were tearful: "Our school was a bronze medal last year."

"Our school did not allow girls to enter school a hundred years ago." Jiang Yubai suddenly raised such a point. He said: "Tradition is not a law, it cannot be immutable, Lin Zhixia, you are a very good student."

As soon as Jiang Yu's vernacular voice fell, someone knocked on the nearby window.

Lin Zhixia's seat is by the window-she always likes to sit by the window. She raised her head and looked out the window.

Jin Baihui was standing outside the classroom of Class 17, holding a notebook. Her gaze penetrated the glass and reached Lin Zhixia's eyes: "You took the 24th place? This is the worst place I've ever heard. You didn't work hard at all."
