OI is like a dream.
And dreams will eventually be broken.
At first, I didn't feel very sad.
until today.
At noon, I went back to school to do errands and happened to meet them going to the canteen to eat after training.
"Are you coming this afternoon?"
"no."
"Why?"
“I didn’t even pass the preliminary round.”
"You quit?" Wei Wei was surprised.
"Yes." He seemed calm and calm.
"Huh?" they all said, surprised, speechless, and regretful.
I turned around and added lightly: "Yeah."
I left quickly, not wanting them to see the indescribable luster in my eyes...
That's nostalgia.
Although the dream is broken, the radiant light will definitely be engraved in the heart and evoke endless thoughts.
The beginning of everything seems to be a phone call from the primary school teacher.
Say, there is a learning opportunity.
I participated.
During the summer vacation, online classes started at home.
The first lesson is Hello World
#include<iostream>
using namespace std;
int main()
{
cout<<"Hello world";
return 0;
}When my young hands typed these lines of code and the white characters appeared on the black console, a brand new world gradually showed its heroic appearance.
After studying for about ten days, I was notified that there was a selection.
I went to that super school with the first GD rating in OIerDB and the third best school in the country - ZSJZ .
I also officially met my first OI teacher: Teacher Chen. (He likes to call himself Teacher Jimmy and is the coach of a certain IOI national team)
After passing the selection, my OI career officially began.
In August of that year, I went to ZSJZ to participate in the OI summer camp and started studying again.
One week, we learned about selection structure from A+B .
Those days were indeed very dreamy. There is no pressure to be eliminated, just learning and practicing. Sometimes I stroll in this "most beautiful campus in the country", admiring the pavilions and chatting.
Oh, I also met a person who loves to put up icons and fish every day. Now we are in the same school as me. He is still wild and unrestrained, and his grades are still among the best.
After the summer vacation, I entered the fifth grade.
Still studying, I go there every Saturday morning.
I also registered a JZ_OJ account and started to answer questions and compete in rankings.
Really, its concise and clear pages, high-standard samples, and high-quality questions constitute my first memories of OI.
This semester, we learned about arrays (seemingly) from loop structures
Then, it’s winter vacation.
I only remember one time I accidentally took third place, and then my deskmate went crazy%%%, and when I ended the camp, I got 0.
The 0 explosion this time also reflected my lack of qualifications and paved the way for my current AFO.
It seems that it is still a week and I learned about character arrays .
The new semester has begun again, let’s start learning functions .
In fact, the content is not different, it just has an additional packaging style.
It was quite fun to learn.
But during the exam, I failed again. The idea is correct, but the program is wrong. Then, I was interviewed by Teacher Chen.
I was kicked to Class B and started learning all over again from arrays.
But the teacher cares about me so much, and I gradually feel better and better.
Then came summer camp again.
All previous knowledge points about functions are once again consolidated.
new semester.
I learned an algorithm that I will use in competitions from now on - DFS (because I was too lazy to think of the state transition equation of DP)
Then it’s about playing games like crazy and constantly improving your abilities.
This also created my almost obsessive love for simple algorithms.
winter vacation.
It seems that I still keep practicing, but I have learned to catch fish.
It was very cold there. In my impression, I stood in front of the dormitory building and looked around under the misty sky.
It’s a new semester again.
I was assigned back to Class A.
The coach turned into a cheating Teacher Xiong (I have always admired the teaching methods of this Teacher Xiong)
Playing games every day, getting fucked every day.
Only once did I get into the top ten (out of about 40 people) based on the cheating method.
Then, there was a big elimination test of mathematics + information. It was okay the first time, at least it was for people. During the retest, I couldn’t understand the questions.
I still remember one such outrageous question.
There is a bug on the number line crawling in the positive direction at a speed of 1 unit length per second. Your pistol can fire one round per second to any location. If the starting point of the bug is an integer, please design an algorithm that will definitely hit the bug.
。。。。
If you write randomly, you will be eliminated directly.
But luckily, I was recruited back by Teacher Chen (thank you very much, Teacher Chen), but this time I took mathematics.
Become more proficient at fishing.
I studied for more than a month and finished learning functions once.
Because the new school was not compatible with JZ, I quit again.
Then, I came to ZSYZ.
A school that is neither weak nor very strong.
Start all over again...
And learn, learn, learn...
Because I have a good foundation, I basically come first every time (I came second twice)
The coach's name is JC. He is very passionate and teaches hard.
There is also a coach from a higher level who often comes to teach us math (but he is an OI coach), named scy.
I still remember that winter vacation, it was our heyday, we learned to wide search and enjoyed the thrill of violence; I listened to Scy talking about various mathematics (the most I remember was that he once asked us to overthrow the root equation and write and copy it randomly) , in a daze; at noon, after a hasty meal, I immediately returned to the computer room and played Black Jump off the Cliff; during the lunch break, we challenged the limits of the monitor together and listened to others playing Werewolf; during the afternoon exercise time, we walked slowly on the playground and chatted.
So happy.
But the good times didn't last long. A computer test suddenly caused a bunch of people to quit, but the teacher didn't even say they would be eliminated.
This exam tested basic grammar (writing a snake matrix, full marks), wide search (I forgot that question, full marks), deep search (I also forgot that question, full marks), and greed (a particularly difficult question) Yes, it requires a lot of bit operations, I just scribbled it and cheated 30 points), the median (I cheated 10 points by force).
Then, we entered graph theory...
In fact, I don’t think it’s necessary to do graph theory. CSP can’t pass such a deep level.
It was okay at first, but as I went on, my mind became more and more confused. Listening to Dong Xiaona's hypnotic voice, I felt dizzy and confused.
Copy Dong Xiao's code every day, submit it, and then end the class. . .
Indeed, very confused.
Summer vacation is here again.
We are about to enter the second grade of junior high school.
Because I got into the top 50 at the end of the first semester of junior high school, I already had the heart to give up.
I didn’t train much during the summer vacation, and I was depressed.
In the last four days, the teacher asked us to prepare for the preliminary round (written test), so we picked up the book and scribbled several sets of papers, which was a mess.
But, there is still one month.
One month of recovery training gave me confidence again, and my scores on the simulation paper were getting higher and higher, so I could definitely enter the semi-finals.
However, it backfired.
Just one multiple-choice question narrowly missed the semi-finals spot.
This means that this year, I will have nothing to gain.
I think, after studying for so long, I still haven’t achieved much.
Maybe, I'm really not suitable.
So, I became AFO.
It's a pity that I don't deserve to be called AFO. This is called - retreating.
Looking back, one of my alt accounts was named tyoier (retired oier), maybe that was the reason for this evil.
At this point, the youth with the keyboard tapping is gone.
But, the story doesn't end there.
believe,
Separation is for a better encounter.
The universe is big and life is even bigger
See you later
Another: Maybe my words are not clear, please understand, because I was too excited at the time
