[user:sumku][contest:1029][problem:D — Retaliation][submission:323473269] Dear Codeforces Team,

I hope you are doing well.

I am writing to sincerely apologize for the issue related to my submission ID 323473269 for Problem 2117D, which has been found to significantly coincide with multiple other submissions.

I want to clarify that I did not intentionally share my code or participate in any dishonest activity. It appears that my solution may have been unintentionally exposed or leaked—possibly through public settings on an online IDE or another medium—without my knowledge. I now realize that even unintentional leaks are treated as rule violations, and I take full responsibility for this oversight.

As a sincere gesture of accountability, I respectfully request that this submission be excluded from rating, and that my other problems in the contest be considered for rating purposes. I accept this as a fair consequence for the situation and assure you that I will be much more careful moving forward.

This incident has been a serious learning moment for me, and I am now fully aware of the importance of safeguarding my code during contests. I deeply respect the values of the Codeforces community and will strictly adhere to the rules in all future contests.

Thank you for your understanding, and I appreciate the opportunity to clarify this matter.

Sincerely, Sumku Submission ID: 323473269

[problem:E — Kirei Attacks the Estate][user:sumku][contest:1027][submission:321486648] Subject: Apology and Clarification Regarding Submission ID 321486648

Dear Codeforces Team,

I sincerely apologize for the issue related to my submission with ID 321486648. My intention was never to violate the competition rules. At the time, I only sought help from a language model to debug and understand errors in my code. I now understand that even indirect or unintentional usage of third-party assistance during a contest can lead to rule violations.

With the help of some experienced and respected members of the community, I have since learned about the updated rules which clarify that only source code written completely by the participant can be used, with limited exceptions:

The code must have been written and published/distributed before the start of the round, or

It must have been generated using tools that were also published/distributed before the round.

I acknowledge that any changes to such code must be made solely by the participant and that all usage must comply with licensing and copyright rules. I now understand that assistance from any tool (including language models) during the contest does not fall under these allowed exceptions and is considered a violation.

I assure you that going forward, I will strictly adhere to all the rules and avoid any activities that could even unintentionally lead to violations. Please consider giving me another chance — I am committed to competing with full integrity. If necessary, I understand that this particular submission can be disregarded, but I would like to confirm that all other submissions were entirely my own work.

Thank you very much for your time and understanding.

Best regards, [sumku]
