long long solve(int x, int y)
{
    return (long long)x * 1000000LL + y;
}
            ...
        int x = temp / 1000000;
        int y = temp % 1000000;
        if(x == y) continue;
        long long rev =solve(y, x);
            ...

(temp is 2e5 at most)

Edit: this code actually does something mb, it is just very unintuivite to code it like this.

also found this funny looking change!

Absolute Cinema

I don't get it what people get by faking their achievements and how do they live in that delusion of being good while all they know is how to cheat.

Update: lequoctran181 is now officially red! everyone congratulate him!

Hi, this is me speaking now.

First of all, I have no other words to comment about the past few months. All my feelings and excitement for Codeforces, it is pure and real. Every day I get up, one of the first things that I do is to log in into Codeforces and read the "blog" section. Surely made my day, the people here are fantastic.

I understand what all of you are mentioning, and you could see that 99% of the AI users will "fight back" through comments after being accused. Of course, AI is AI and it is really easy to know that whether someone is participating genuine or not.

No further details, this is my word: "I do use Artificial Intelligence in some of my problems while solving. I felt that I don't want to lie to myself or to all of the users if they get hurt from what I was doing.

Of course, there is no excuse that could make me even 1% right. I'm wrong, I'm really wrong. It's 2AM in my country now, I feel so guilty and so bad that I have to get up and post my final message here. In the first tens of contests, I joined without using any AI. At that time, I thought that I had to practice really hard if I want to move further to ICPC APAC 2025. At some time, I reached 1600. Till now, I still believe that I am around 1700-1800.

But of course, that isn't enough to move on. So I remembered this deeply: "if I want to join the contest next year, I have to be well-prepared for the contest next year". I felt terrible that this is when I started coming the wrong path.

It all starts when I want to organize my own contest. For real, actually now I have 25 problems ready to be released in a contest. At that moment, I thought "will someone believed in my skills if I'm only 1600 likewise". That is when I started using LLM. I solved the problems fast with multiple lines of code, that is what I can really do. I would never thought I came deep as a mistake like this.

I know that no one wants to forgive what I have done. But please, I want to have a redemption. I really love competitive programming, it means the world to me know. After this post for 12 hours, I will delete my account and I will rest and criticize myself for a time, probably about a month, for how wrong have I been to the community and the amazing people here. After that, please in the deepest of my heart, I want to open another account in which I will promise I joined every single round, every single problem with integrity and always learning to achieve better performance and awards. I beg you all, can you give me an only chance to really redeem what I had did?

I know that with this, my project of problem setting must be cancelled. But if I am able to have a last chance to join the rounds with dignity, one final last chance, I promise I will never violate any single rule here. beaaaan, I really want you to offer me one more chance so that I would further improve my skills. I will create a new account and start all over, with only passion and integrity.

I wish all of you the best of health, may peace always stays with you. In the next 12 hours, if you have any questions, please fell free to ask me. I will answer all of the questions honestly, Really, really sorry, for everything.

beaaaan ur my hero

salute to https://codeforces.me/profile/beaaaan

Yay, he got banned

I think it's sad that AI is "corrupting" a lot of people nowadays. Why would you have to study chess (to an expert level) if there's an AI in your pocket that's capable of beating Magnus Carlsen? The same thing goes for CP.

The thing that makes me scared the most is the fact that with AI, many students actually use it to finish all of their work and fool teachers instead of actually learning new things. It could lead to an unskill generation of coders, which should be harmful.

A student argued with me about why we have to learn how to program if there is an AI to do that for us. I mean, plug-everything-from-an-AI-without-understanding-anything is not a great thing to do =)))

(P/s: sorry for my bad English)

I think i fell in love with beaaaan

Also update: not only this guy lequoctran181 was banned, but he also locked his Facebook profile.

I wonder why

What's wrong using unordered_map?

Damn. You really made bro reflect on his actions and repent.

Lol bro cheated and went into ICPC

It never even began for him.

My train of thoughts at the end of the blog:

"Who are NEU.Newbies? I swear I had been monitoring the scoreboard of VN site in and out on contest day and this team never scored any remark in my head?"

"Oh... 4 solved, struggling hard on 2 trivial ones."

...Truly a red performance.

The fact that AI can do this well not only on Codeforces but also in USACO and AtCoder is very concerning

Just a frustrated penguin here from Heard Island Spent months solving dp problems in the freezing cold , dreaming of becoming a Grandmaster Now people just use AI to get there with zero effort And as if that wasn’t enough, America’s throwing tariffs on our poor island too— for what, frozen wind? With AI taking over and ice getting taxed, even trying feels pointless now
