Hi everyone!
Today, I'd like to hear the opinions of people who participated in this round or solved Problem F.
I noticed a contestant whose submission timeline caught my attention. During the contest, they submitted an accepted solution roughly every 30 minutes. They solved only Problems A and B before eventually getting an accepted solution on Problem F, which is a significant jump in difficulty.
To better understand how they solved it, I contacted them privately after the contest and politely asked them to explain their solution, including the main idea, the algorithm, and the implementation.
However, instead of receiving a technical explanation, the only reply I got was:"like u think"
After that response, I honestly didn't know what to think. It made me wonder whether there might be something unusual about the submission, but I also understand that this response alone does not prove any wrongdoing.
So I'd like to ask the community:
- Does this progression seem unusual to you?
- If someone legitimately solved Problem F, would you normally expect them to be able to explain the core idea afterward?
- Are there reasonable explanations that could account for this situation?
I'm not accusing anyone. I'm simply looking for objective opinions from experienced competitive programmers and participants of this round.
Thank you.
As a cheater exposer (that's how I call myself lol), this blog is kinda trash, like you provide no evidence beside what you think. In fact, I'm investigating this case myself. My intention is that, the 4th episode of my series will be about Prototype1510.
Thanks for your feedback! I really appreciate it. This is actually my first time writing a Codeforces blog, so it's probably a bit clumsy :((. My intention wasn't to accuse anyone, but rather to hear opinions from people who participated in the round. I'll definitely try to do better next time. Looking forward to reading your investigation!
Still, I think that this blog is better than most of the other exposing cheater blogs.
I think the suspicion is understandable. Spending almost an hour on A and B, then solving F in just 26 minutes is certainly an unusual progression. It doesn't prove cheating by itself, but I think it's reasonable to ask for further review, especially considering the response when asked to explain the solution. Here's the submission timeline: here
These are the words that the Prototype said: https://drive.google.com/file/d/19WpsHjwhaL7urBqxayVoX-PrEqIFUFAw/view?usp=sharing https://drive.google.com/file/d/1dZjQOGlBFKCYuePkGcB1wiW2sL5vAhCg/view?usp=sharing
This is Vietnamese, in English, he means that:
nah I'm too lazy to translate you have google translate right
In short, he admitted that he used Gemini pro on F
Summary : This guy is only Specialist, but he believes that using AI on Div. 2 Problem F still reflects your actual skill level. On the other hand, he thinks using AI on Problem C isn't acceptable because it no longer represents your real ability.
Oke e zai
Deleted, because someone wants me to delete this. Please don't check the previous revision.
chill:vv
ok e =))))
ok =)))
are you kidding me?
Nope =((
oke a =(((
ok e zai luôn
tốt e
As he admitted that he cheated (according to hunglvh's comment), I think that he should be
thrown to cry's basementmarked as a cheater in the database. However, I think that he shouldn't be banned, because he DMed my friend CheaterGotTalent, saying that he is regretting now/Regret is not an excuse to let him continue cheating
He continue to cheat? hell nah...
Nvm, he deleted the blog. I guess I'm right then
I'm sorry :(((
Apologizing is not going to change the fact that you are a cheater
i know :(
