Hi codeforces! Today I noticed a very suspicious attempt by a [user:https://codeforces.net/profile/tourist] on the last round of [submission:https://codeforces.net/contest/2066/submission/305616029]. I think he is using chatgpt. Please [user:https://codeforces.net/profile/sevlll777] take action and ban the [user:https://codeforces.net/profile/tourist] for using AI on the round.
