### Potential Cheater / AI Plagiarism in Codeforces Round 1098 (Div. 2): [user:_kiran_iitm,2026-05-17]↵
↵
Hello evryone ,↵
↵
I would like to bring to light a very obvious case of cheating/plagiarism during the recent **Codeforces Round 1098 (Div. 2)**. ↵
↵
The user in question is [user:_kiran_iitm,2026-05-17].↵
↵
#### **The Evidence:**↵
If you look at their submissions for this round, it is highly evident that the code was generated by an AI and copy-pasted directly into the judge without even cleaning up the comments. ↵
↵
* **AI-Generated Comments:** The code is flooded with redundant `//` comments explaining basic algorithmic steps and boilerplate code. It even includes typical LLM-generated comments like `// FAST IO` and step-by-step logic breakdowns, which is completely unnatural and unrealistic for a participant during a live, timed competitive programming contest.↵
↵
#### **Submissions to check:**↵
* [submission:374825254]↵
* [submission:374821053]↵
* [submission:374812733]↵
↵
This kind of behavior completely ruins the rating fairness for hard-working participants. I hope the coordinators and Mike take a look at this case and take appropriate actions.↵
