False Plagiarism in Round 908 (Div 2)
By X-OR, 12 months ago, In English

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

Just seeing from an outside perspective, all of the codes seem too similar. All yours is different in, is missing the word "unordered". All of the other accounts have some similarities. Seems suspicious.

For example: How can you explain the similarity between codes of problem C?

Too similar

If you are cheating along with these people, it's just a shame. If not, I hope you prove your innocence and get justice.

    First of all I don't know these people and regarding the C submission atleast check my submission too before saying about the similarity....

    My C submission : link

    When the problem tells u to implement a straightforward solution there is bound to be some similarity in sols even the editorial had similar sol for B where it was just trying to implement the first two conditions.

Why are all the solutions so similar? There is strong evidence of cheating. Don't attempt to deceive everyone by posting such content just to cover up your cheating. The probability of having so many submissions that are similar to each other is very low. Practice more instead of resorting to cheating in contests.

    When it's a div 2 problem B the ideas are surely gonna be similar for lots of people with such thinking everyone should have gotten plag for the A problem if it's just returning the last character of string but that's not the case.

Lol, more ChatGPT content.

Also, the solutions are basically the same. Same C++ features, same lines of code, all that's changed is the variable names. I wouldn't be surprised if they compiled down to the same assembly if you changed your ordered map to an unordered one.

    yup it is all same just changed in variable and just for sake use map instead of un_ordered map
