Hello!

I recently received a notification from codeforces stating that my solution for problem b was flagged for similarities with other submissions, resulting in my disqualification from the contest. I believe this is a wrong accusation since the problem required a straightforward implementation of two conditions, leading to resemblances in solutions.

Upon reviewing other submissions, I identified some differences in my code, such as my use of an ordered map, whereas all the other submissions used an unordered_map. My coding style, indentation spacing, and input/output formatting remain consistent with my previous contest submissions, which is notably different from other submissions. This suggests that the alleged similarity is coincidental, and I am falsely accused of plagiarism.

MikeMirzayanov please look into this and reconsider my submissions to make this contest rated for me. After grinding competitive programming for almost a year now it would be stupid for me to resort to copying solutions at this stage.

Here is my submission : link



Here are some other solutions which were mentioned in the message I received :

Submission 1, Submission 2, Submission 3, Submission 4, Submission 5

I have commented about the same -> here

I got to know about arbitrary code execution (ACE) which is an attacker's ability to run any commands or code of the attacker's choice on a target machine or in a target process. Therefore I was thinking how does codeforces prevents such attacks on their compilers or have they taken and preventive measures for such vulnerabilites.
