First put my own information first, I am a very ordinary OIer, but I want to solemnly bid farewell to my OI.

experience

Talk about running accounts.
Why do I say there is a difference at the end of eight years, because I have been learning programming since the fourth grade.
Our place is called Cixi, and our Xinjing system was implemented from the elementary school.
I am the monitor of our class. I belong to the elite students in my grade. I was pulled out to learn programming at the beginning of the fourth grade. I was repellent at first because I didn't know anything, and several people in our age had already studied in Gaode (training school) during the summer vacation of the third grade, such as my classmate, Zhao Yipeng .
Our beginner is $pascal$ , I didn’t even know the word at first, the$begin,end$ I memorized it directly. It's very mechanical. After learning for a long time, the teacher talked about converting between uppercase and lowercase letters. I find it a bit difficult.
By the way, our programming teacher taughtLai Yanyan, but I can't contact her now. She is my enlightenment.
I had been in the fourth grade and had to give up several times, but I don’t know why I have been in the programming class. At the beginning, a large group of people dropped out one by one. The teacher valued me because I was still studying in AutoNavi’s Mathematical A class. Ten levels. It belongs to the mathematics gifted in Cixi City, so I must stay.

I don’t know how long it took, and I reached the second volume of the fourth grade, and started to learn sorting algorithms. Teacher Lai first told me about bubble sorting, but I didn’t understand it. Teacher Lai told me about the selection and sorting. Now I understand it. My thinking is a bit slow, so I don't know how to draw analogies. But gradually, I still understood how to sort by bubble. I still remember that we did a few classic questions about
compartment reorganization, obviously random numbers, k-th small integer...
I entered the High German programming class during the summer vacation of the fourth grade, and started directly from the second class, but the result was still sorting. , I have no pressure to maintain rk1 results.

In the fifth grade, we began to prepare for the primary school competition in Cixi City. I have forgotten the specific details, I just remember the final 90 points and won the third prize. Five times, I participated in the programming competition for elementary school students in Ningbo. I remember that the test site was Jiaochuan Academy. I was very excited at the time and finally won the third prize. Lao Zhao (Zhao Yipeng) probably won two second prizes, and then signed a contract with Shanglin with Hu Siyuan .
The fifth grade teacher Lai began to teach us the backtracking algorithm, which is $dfs$ , but I did not understand.
During the summer vacation, I was in the fifth grade class in Gaode. The teacher isLu Ping. I have to say that Lu Ping is indeed very good. After he took the first class, I understood what dfs is all about. The only time of the four exams in the fifth grade was when there was no AK accidentally in the mid-term exam. He took 395 and was surpassed by two people.

Entering the sixth grade, surrendered the members of the brigade and started to salt fish. Fully prepare for the programming competition for primary school students in Cixi City. At the same time, I came to Shanglin Middle School to learn programming. I met a lot of future friends here. For example, Ouyang Wangjie , he didn't expect him to learn programming.
The preliminary round was 95.5, rk3 in the city. Chen Yiyang is on the left in the rematch , and Xu Jia is on the left . I took 190, wait a minute. Hu Siyuan ak, rk1 in the city.
During the winter vacation, Shanglin invited senior Gong Jiyang to come to class. Everyone is here, Ouyang, Fang Xingkai , Zhang Yichao, etc. Ouyang scored rk1 and I scored rk2.
Six times, continue to participate in Ningbo Programming Contest, 210, first prize.

Our summer vacation officially joined Shanglin, teacher Zou Zhongjie (Zou sir) directly points the group, from which a lot of people picked the nine people as elite. Hu Siyuan, Ouyang, Chen Yiyang, Qi Yang , Fang Xingkai, Sun Xulei , Hu Ruiyang , Zhang Yichao and me. Old Zhao was exiled to the second echelon by Sir Zou because he took two third-classes in the sixth grade.
We learn with someone who is one level higher than us, and I play fairly averagely.

In 2016, the first day of junior high school, I met a lot of new students. I won’t talk about it here. I participated in the popularization group. After the preliminary round, I got a fever in the semi-finals and I was very confused. There were four violence written in the examination room, 100+100+70+50=320, and I won the first prize directly, which I never thought of. Participated in the Ningbo Junior High School Programming Contest, 100+100+100+70=370 won the first prize.
In the first echelon of our year, six of the nine people I mentioned above are first-class. In addition, Feixu (Sun Xulei) had a wrong file name 325->225, which is a pity.
I continued to study in the summer vacation of the first year of middle school, but at that time my level was actually very low. Many algorithms were not good at it. I did it based on my feelings. During this period, Shanglin invited three Ag seniors to give lectures, namely Ren Luyao and Xu Yewen, Hu Zhenwei , both went to study military after graduating from junior high school.
I also did a very interesting event during the summer vacation, that is,


I was just ignorant. I apologize to luogu. .

In the second grade, we continued to participate in the popularization group. Sir Zou asked us to prepare for the improvement group, but only Hu Siyuan and Qi Yang participated in the improvement group.
I came into contact with the algorithm by chance, and I came into contact with it in Luogu. I learned tree arrays, st tables, line segment trees and so on. Participating in the popularization group, that year was the topic of hopscotch. I saw a monotonous queue , but I didn't call it out, so it burst 0. I wrote spfa for T3. I didn't have a big sample, so I taught a violence.
In the end, 100+100+50+0=250, and won the second prize, which is very shameful.

The summer vacation of the second year of junior high was a period of my evolution. I finished my self-study of all the algorithms in the improvement syllabus. I also opened CSDN and started to record my questions in the blog.
At the beginning, the first echelon took the first-class six people. Three went to the army to study, and two went to Hang Er to study. I stayed in Shanglin because I played so badly in the second grade.
But I just brushed up the questions silently, doing almost all the real questions in the league over the years.

The third grade is officially ready to improve the group. In the preliminary round, he tested seventy and one point and lay in the semi-finals. Zhou Xiaohe also participated in the improvement group. He played particularly well in the second grade at 345, but he was training in Cixi Middle School , so I was the only one who stayed in the Shanglin computer room to participate in the improvement group.
In the semi-finals, I put the travel notes on the top, I played supernormally, 100+100+75+68+75+44=452 took the first place, only Ouyang in the school was a little higher than me, my rk2.
also this year, We got 6 first-class in Shanglin, but Zhou Xiaohe didn't play well. At the peak of history, in the next two years, Shanglin did not improve. Because Sir Zou is outdated, he doesn’t know about innovation. The 5 of us in this class have first-class strength through studying in the second place in Hangzhou. I have the first-class strength in Luogu by chance, and there is no guide for the subsequent students. . Sir Zou can't keep up with the times. Xin Jing from Cixi High School and Lu Ping from Chongshou and the old money from Experimental Middle School are OK. Shanglin must change.

Entered the innovation class of Cixi Middle School, and started to study in the Xinjing team of Cixi Middle School in the third grade. Fang Xingkai left the Xuejun and returned to Cixi Middle School. The two of us who had been improved in junior high school were the leaders.
There are two seniors in Cixi Middle School who are one level higher than us. They are Zhang Yucheng, Zou Liushi , our 5 new senior high school students , I, Fang Xingkai, Lao Zhao, Zhou Xiaohe, Ni Nan , and two senior high school seniors to join the provincial team. Selection. I scored 30 points on day1 and 80 points on day2. My level has not yet reached the advanced level.

In the summer vacation, Fang Xingkai and I went to Shaoxing No. 1 Middle School for a training camp. There I met a lot of very good people. I have to say that Shaoxing No. 1 Middle School is really professional.
During the period, I also played the NOI synchronized match and scored a total of 200 points. If I add a written test, I should have a bronze medal.
It's just that I am not qualified.
The experience of Shaoxing No. 1 Middle School is really rare. You would never have thought that two people just explained the topic to you on the podium. A few days later they went to the NOI stadium and won the gold medal.
I would never have thought that Zhou Yuyang and Wang Zhanpeng, we were so close at hand a year ago, and a year later, the two of them represented China's gold medal at IOI.

In the first year of high school, we participated in CSP2019, and I was 73.5 in the preliminary round and lay in again. In the semi-finals, 100+100+20+64+64+75=423
Fang Xingkai is 5 points higher than me, but our school has only 5 first-class, and I have already had first-class strength at the same table, Feixu , There are old friends Zhao, and senior Zou Liushi.

Fang Xingkai and I went to the winter camp of Peking University, where I was abused. I have seen a great world, and it is a worthwhile trip.

Then it's this year. The epidemic made me give up OI, and I basically never wrote code. As a result, my level has not improved a lot, or even regressed.

I regained OI in the summer vacation a few months ago. I want to participate again. This is an experience.
There were many lovely classmates in the new high school, but they were rather decadent at first. I thought their learning method was wrong, so I became a keyboard man.

Especially funny. Of course, what I say now is also to explain that I am not entirely right, because I am also a better cook now.

Then there was the preliminary round. I was more suitable for this kind of written test when I was older, but I was still a little careless, with only 88 points.
The CSP rematch test was very poor, and the travel notes were also at the top. This time, in the entire CSP school, Feixu and I won the first prize, and we stepped back.

Then, it was yesterday's NOIp. I played mediocre. I don't know the result, but my estimate is 210~270.

The above is all my experience, there may be omissions.

I don’t know if you have seen such a sentence.
If you were told that you had 20 days left in your life, what would you do?
One answer I have seen is that
I will continue what I am doing, and when death comes, I will let it go, or finish it. In short, I will welcome death peacefully and indifferently

This problem was faced by me 20 days ago. I really only have 20 days left on my OI road, so I will experience this thing in the end. This feeling, I also wrote in the top CSP2020 travel notes.

people

People are the most important thing in society. So let me talk about all the people I know who are related to programming and OI.

teacher

The enlightenment teacher is Teacher Lai Yanyan from the Fourth Experimental Primary School in Cixi City , but now I can’t find her.
Gao De has two teachers: Wang Longqiang and Lu Ping, and
Shanglin’s teacher, Zou Zhongjie, the
most important
teacher, Sheng Xianliang , Cixi Middle School. Teacher
I know Mr. Sheng the best, and I have talked a lot with Mr. Sheng. As for who I am most familiar with in Cixi Middle School, it must be Teacher Sheng, even the class teacher is hard-working and thrifty.
To say that in Cixi Middle School, the teacher who knows me the most, is definitely Teacher Sheng.
Thousands of words, in short, I am very grateful to the teachers who taught me and I am very happy to meet them.

Senior

My elementary school is the fourth experimental elementary school.
There are two seniors two years higher than me, Chen Weiyu and Shen Fancheng , and they both entered Shanglin later. Chen Weiyu is our pride. He later entered Hang No. 2 Middle School and got Au to enter the National Fair.
There are two seniors one year higher than me, Liang Jun and Wang Zeyu . The former went to Zhenhai Middle School and the latter went to Xuejun Middle School. But their results are not as good as mine.

My junior high school is Shanglin Middle School.
The oldest brother is Gong Jiyang. He also went to Cixi Middle School to get Cu.
Then Ren Luyao, Xu Yewen, and Hu Zhenwei.
Then there is Xie Jiadong , my best friend . He is now playing ACM at East China Normal University and he is very strong.
Then is taller than me-third of (this name is really good) Chan Tinto, sinker Wen, Wang Kai music, Yeltsin
taller than me two of Chen Wei Yu, Shen Fan Cheng, Rong Rong, Sun Yang He, Cupid, Huang Yang Bang, Sun Jiajun , etc.
than Chen Haoyang and Pan Sicheng , my first-year high school students , both went to school. Zou Liushi, Chai Haotian, Wang Ruotian, Sun Yiyang, Zhu Zhekai, Chen Qihang, Chen Zhedong

My high school was Cixi Middle School.
There have been three gold medals
in history: Zhou Yifan, Cen Yukuo, and Chai Hanfeng have won
a silver medal, and Ye Siwei (this one is also from Shanglin)
has won a bronze medal and Gong Jiyang.
I'm not familiar with other non-Shanglin seniors.

and Ni Nan were in the same class in junior high school. They are currently in the same computer room. They just separated yesterday.
Shen Xuran and Huang Peilun are good friends now

Hu Siyuan, Ouyang Yongjie, now in Hangzhou Er, have not seen him for a long time.
Chen Yiyang, Qi Yang, are now in the academic army.
Four of them are junior high school classmates. The relationship is very good.
Qi Yang is still working hard in the academic army. Enter the team and get the Au from NOI

Chen Jiacheng, my younger brother, hope for the future of Cixi Middle School. I hope that Chen Jiacheng can continue to do so, even if he fails to get results, continue to pass on our spirit.
Wang Yukai, my school brother. Hope for the future of Cixi Middle School. I don't know that he may not pass the exam, but he is capable. I hope he can pursue more important things in Xinjing, not just achievements.
Zhang Yufeng, my super direct school brother, is in the same elementary, junior high and high school. He is very talented, but he wastes a lot of time. I hope he will not waste his talent, we can all do well.
Ren Haochen, Li Jialu, Zheng Yi, Zhang Tao, several of them will continue to work hard.

Huang Xuze, Huang Jiale, Shen Tianchen, Wu Yuyang, Hong Huayan, Huang Enhui. You must find the right direction, you are all more talented than me.

Chen Yufan, this is the son of a mathematics teacher in our Cixi Middle School. I am not particularly familiar with him now in the second grade. I hope this student can come to Cixi Middle School and continue to engage in letter competition. You are the hope of Cixi Middle School.

Chen Hongji, this is a person I just found a few days ago with the same nickname as me. Far in Guangdong, I hope you will continue to work hard to achieve your own dream.

Goodbye

Finally, let me talk about my feelings.
The epidemic has made me a lover of literature and history. In addition to Xinjing, I can also study our history in China. I think reading books is a very happy thing. Just now, Huang Guangsheng talked with me for a long time. I said, reading books will make our hearts stronger.

I started to learn programming in the fourth grade, and everyone around me fell down and retreated one by one. I have survived till now. The fourth grade is 2013; now it is 2020. Eight years . It's an era.
I think what Xin Jing has brought to me, many, many, we think differently from ordinary people? Unconstrained, eclectic imagination and style of life? Xin Jing keeps me from falling into clichés and makes my life denser. It gave me guidance in the direction of my existence, and gave me the courage to erupt my life force. There are too many, I can't finish it. For eight years, Xinjing has been integrated into my life's blood.

Human company. For more than 17 years, I have met very few people. A large number of people are from Xinjing. I am very happy to meet so many lovely people. I am very grateful for my company.

I think, what kind of big things we can do.
I think it took me three years to do one of the biggest things in my current life.

This is my achievement, 498 original blog posts, 9W+ interviews Volume, my blog is my accumulation over the past three years, and it has helped many people.

It’s very strange that I suddenly discovered that my chairman tree blog post disappeared in Baidu, but my article was listed on Baidu for nearly a year


. It helped thousands of people learn one. Algorithm, this is the most meaningful thing I think I have done.

There is also Cixi Middle School. I cherish my time in the Cixi Middle School Xinjing Team. I retired. We passed the baton to the first year of high school. You are the next hope.
Ouyang Xiu's mentality became more stable in his later years, and the maid asked him why Ou Gong kept laughing? Ou Gong said, it's culture. The maid was puzzled.
Ouyang Xiu knew that he had passed on the baton of Chinese culture to a stronger person, Su Dongpo.

The first year of Cixi Middle School is more vigorous and powerful. The second year of high school is retired. I hope you will shoulder this banner and live up to yourselves.

I'm sorry that there are three names in red because the black letters are not obvious.
Next, Cixi Middle School depends on you.

Goodbye.
