About This Div.2
By zhoujiarun0216, history, 12 months ago, In English

The Div2 contest has ended, and I was extremely lucky to solve 5 problems.

I was 30 minutes late to this contest because I had to have my meal.

Problems ABC were straightforward. For problem E (extended Euclidean algorithm) and problem F (linear basis under GF(2) with Gaussian elimination), I happened to be studying these topics recently, so I managed to solve them by sheer luck.

I know many will accuse me of using AI—go ahead and say that. The truth will speak for itself.

Finally, Amao_Fox, our bet has been settled.

I don’t believe AI could solve problems E or F. To prove myself, I documented my own thought process in solving problem F.

    Just wait and see, if you can get 220pts in next CSP-S and NOIP(if the difficulty is same as 2024), then I(perhaps we) will apologize for seeing you as a cheater, otherwise I will seeing you as a cheater forever. Don't say something like you wrote 250pts and because of freopen->feropen you actually get 50pts.

Maybe if you had the premium version you could have solved D as well. Seems like you are too poor for that. Pity you :(

first attempt on 2B

second attempt on 2B

Why you changed the number of tabs and spaces and nearly rewrote your code in only 8 mins? I don't think one will even change such things in a competitive contest where time is very important.

    There were issues with my code, so I refactored it right away. Additionally, I always format my code with VSCode before submitting, but I rushed the first submission and didn’t format it.

/*
n=奇数，需要s=t；  
n=偶数长度时**，分解为 n 刨掉每个2因子这么多的块。  
XOR 操作就做同一组可逆线性变换：t = ms 对所有块内对应位置同时生效，且 m 必须可逆。  
存在可逆 m 使得 ms = t 就是s 的行空间要和 t 的行空间一样
那么我们只需要找到所有块，做 GF(2) 下的高斯消元，再把 s 的每个块在 t 的基下消元，全部化为0。
同理把 t 的每个块在 s 的基下也能化为0，代码比较好写。

What is ** in the third line? Is it bolding in markdown? Why is there markdown in your code?

Did you reach free plan limit for o4-mini so that you had to submit after 30 minutes?

This is your attempt on div2B: https://mirror.codeforces.com/contest/2098/submission/317300434

I copied the whole statement on to ChatGPT and it gave me this: https://chatgpt.com/canvas/shared/680cd609ddd48191adaae6f0cf1189b6

Yeah, someone bans his account because it is just funny if he does not get banned

    For easy problems like AB in div2, the solutions are mostly similar, right?

      Yes, in fact the differences bewteen everyone's solutions is just the variable names. The templates, indentation, the logic in every line is the same!

      Like seriously who are you fooling. You declared vector<ll> a(n); and vector<pair<ll,ll>> segs; segs.reserve(k+1);, I do not think you know what your code does, you only know how to delete comments that ChatGPT gave you. What a pity, if it does not give you comments you can submit it even faster!

      Honestly I think you are trolling here and I am wasting my time.

So why didn't you write down your thinking process in the code comments in E?

Everyone, look at me.

I apologize. I sincerely apologize.

There have been too many people in history like me who tend to make mistakes and lead to significant errors. Now I am convinced that Zhou has this strength, he even made an F, and our entire computer room later discussed how to make F.

I really believe that there is nothing suspicious about his entire process, and all the details are even more normal than normal. There is nothing to nitpick about, and I don't want to refute any of his words.

The above content is definitely not false.

Meanwhile, according to the agreement, I will discard the account and never use it again from now on. I voluntarily withdraw from Codeforces. If there is any turning point in the situation, please notify BouncyHunter and they will inform me offline.

Zhou, Are you satisfied?

    I guess you don't need to apologize to an account with a fake identity, controlled by another person who also cheats shamelessly in contests to IM.

if you try to solve d using ai, then you would receive numerous [wrong answer]s and then finally give up.

I believe you can solve all the problems in the Edu round tomorrow by using AI and become Master, and I also believe you can solve all the problems in the Div. 1 round on May 3rd and become Legendary Grandmaster! That will prove AI can get LGM

Of course, be careful with your account, it may be banned at any time
