DP for success, DP for failure (AFO?)

Don't know what to say. .

I've never written a blog, and I don't know anything about markdown, so let's take a look.


When I was in junior high school, I started to engage in OI. After two months of learning, the popular group broke out and retired.


When I was in the third year of junior high school, I said that everyone had to choose the competition, and I chose the information with a mixed mentality. At that time, I just wanted to play on the computer for two months before I quit the competition, and then I fell in love with DP.

At that time, I thought DP was really fun. A seemingly difficult problem could be solved with 20 to 30 lines of DP code. Then I thought that the information might be quite simple. Anyway, there was not much time for the weekly competition, and it was OK . Depressed , it will not delay the subject, what if I take it and save it?

Then began a decadent high school life.


I remember forcibly not going back to bed at noon every day, and I was in the computer room with a few classmates. At noon, I was either cs tring or watching, playing Clash Royale. oj rank. I haven't heard much of Mr. Wang's lectures every time. I want to sleep every time I give a lecture. Anyway, I think in my heart, it's okay to be a jerk.

Then the league unexpectedly exploded.

It seems to be 168 points. In fact, if you remove your small mistakes, you should be able to get around 350 points, and then you feel inexplicably hanging?

It was the first time that I felt that I was still a bit strong, but I still felt that it made no difference whether I learned new algorithms or not. After all, I also used Deep Search, Heap and DP in my league, so I still didn’t take Mr. Wang’s lectures to heart.

It wasn't until others learned more and more algorithms and data structures that I didn't even know anything about line segment trees. The big guys next to me are all forging ahead, and I am still like a boat against the current, I have been retreating, I just realized that I wasted a lot of time on the slump.

Several exams during the winter vacation proved that what I said was correct. Looking at other people, I could casually ask A question, but I couldn't even understand the solution.

Then came the provincial election, got a score similar to the league, and the first year of high school was almost over.


Sophomore.

Mr. Wang left us for physical reasons, and Mr. Li took over. The first impression of Mr. Li is that he is approachable and full of energy. Under the leadership of Mr. Li, I had a rare passion for the competition. Although I also started the competition conscientiously, the results showed that I was indeed inferior to others.

Until that time, I went to the training of Pei Chui abuse of vegetables .

Originally, I didn't have much confidence, because on the first day of the exam, I didn't even pass the first-year high school tycoon, Oldfish.

Then I AK three times.

Those were some of the best exams I've ever taken in my life. For four hours, I was able to keep every minute and every second just right. Every time I finished the exam, I was full of energy. Those sets of questions seemed like they were born for me. Prepared (although the data structure problem is still zero).

What impressed me most was what Coach Zhou Zusong of No. 1 Middle School said to me:

"Do it well, you can enter the provincial team." (Poisonous milk!)

That sentence is like the rain after the rain, which gave me a lot of confidence.

Then I started a long process of checking and filling the gaps, and slowly picked up the knowledge that Teacher Wang taught me but I was deaf.


However, I still can't change my habit of loving decadence, minecraft, Warcraft, cs string , deepeep, neverball, force, billiards, generals...

I can read out a bunch of games that I've played in the computer room at least a hundred times (cs string , deeeep, generals, neverball, probably thousands of times), and they've basically poisoned the freshman.

At that time, I just felt sorry for my youth, but now I feel sorry for those high school seniors.

I'm very sorry for the handsome and titan Jiacheng. He kept taking him around before the league. As a result, he didn't do any studies and wasted a few months. Moreover, he was still in the same class as me.

Before the league, I was still blindly confident, because every time I could rank the top 3 in the basic exam, and then I only supplemented the content of the league, and the rest of the time was wasted all the time, but other high school seniors have already completed the knowledge of provincial elections.


League 455?

It's not a very good result, it's still a little short of the estimated score of 500, but it's not bad.

Looking back at the juniors in the first year of high school, the oldfish giants and the gods are all provincial one.

Just look at the high school...

The three who didn't take the provincial one, including the handsome and most handsome Jiacheng, really feel very guilty for him.

The next step is to prepare for the election.

The result of 455 has little advantage in the provincial election, so the provincial election still has to go all out.


During the winter break, something happened.

PKUWC?THUWC?简直有毒。

本蒟蒻只进了PKUWC。

上午数学,下午机试IOI赛制。

上午还好,下午差点心态爆炸。

还剩30分钟时,40pts,rank100。

T2想了两个小时,最后30分钟才想到DP正解。

最后5分钟,A了T2,140pts,rank30。

第二天130pts,rank70。

总rank28?简直有毒。

A的两道DP题带我飞。

意料之外的拿到了一个D类一本的约,算是非常好的了。

当时觉得,一本稳了。

接着在WC2018被虐翻,拿了个狗牌,不过确实一道题都不会。


寒假后面还是收了心了,虽然说还是有时候会gen。

高级数据结构,计算几何和数论还是都搞了,但都拿不出手,字符串只会KMP和AC自动机,还是省选前一天背的模板。

FFT学了又忘,NTT考试早上六点学的。

省选前几次模拟考试都是看了觉得不会就睡一上午,然而别人都切了题。

永远都是在临近考试前才感觉到危机感。


省选。

D1早上起来看新闻,发现阿森纳客场绝平晋级四强,心情稍微放松了一点。

到了考场楼下又强行背了一波NTT和对拍模板。

打开题目,看了30分钟发现自己一道都不会做,直接暴力走起。

最后一直在肛T2,然而什么都没搞出来。

下午看成绩80,rank50。

后来发现T3还有55分暴力没拿,后悔万分。

晚上一直在吃鸡,单人四排莫名吃鸡233。

D2早上起来还是背模板。

考场自我感觉良好。

T1一看就是奇怪的数据结构,60分暴力拿满就好。

T2一看就是奇怪的数据结构,40分暴力拿满就好。

T3一看就是奇怪的数据结构,20分暴力拿满就好。

出考场,T1鸡哥A了,T2贪心,T3普及-DP,noip难度?

我觉得我van了,估分才120-140。

下午吃鸡和lol都装比失败,连续落地成盒+送快递+对线被压着打。

结果出来130?T1有20pts?T2有90pts?

样例全错的贪心90?

第一题40分没拿到又是什么意思?

而且D2T3这道普及-DP又是什么鬼?

真的是什么不擅长的都没考,还考了拿得出手的DP,结果还没做出。

可能是PKUWC那边A的两道DP是我欠的,而现在又还了吧。

真的是成也DP,败也DP。

rank44?也许还有机会搞个D吧。

不管了,考都考完了。

申诉什么都没搞到,还被教授嘲讽了一波。

听说喻队被初二的抢了省队,心里更加不爽了。


HNOI重测?

结果我D2T2少了40,喻队进队了。

还是要恭喜一波喻队了。

D类不用想了,已经没希望了。

只能寄希望于CTSC和APIO,虽然我觉得我应该也没什么机会了。

再见OI?AFO?


让关心我的人失望了,对不住自己对不住他们也对不起高一的学弟们。

高一学弟们好好搞,我已经丢了学校的脸,未来就看你们了。

generals什么的少玩,安心竞赛,我还是非常看好的你们的,毕竟你们现在学得比我还多。

如果一个选手比你小,还比你强,那你就打不过他了。

也许到了暑假你们都要看不起我了吧,毕竟我什么成就和用处都没有。

加油吧,少年!
