I received this message from System

Attention!

Your solution 39098512 for the problem 990A significantly coincides with solutions alekseev.aleksei/39090526, GustavK/39098512. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.com/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties.

But I didn't cheat and it is impossible that anyone took my solution. The solution mentioned is not even similar to mine, it is in Java and my is in C#! There is absolutely not a chance we copied each other. And how can "Such a coincidence" be a rule violation? How am I supposed to write code avoiding such a coincidence to not break the rules!?

So do I need to do anything to fix this or can I just ignore it? Is there a chance I will be blocked if this happens again?

Judging by these two submissions only, it looks like a system glitch for me. I think there is a chance for subsequent bans, so it's better to appeal early.

KAN, mind taking a look? OP's submission: 39098512, similarly looking submission: 39090526. They're indeed similar, but that's not unexpected in problem like this, I think.

what yeputons says is right. There is a more chance that problem like this have same solutions. As these problems are very obivious! But you should talk to them with your reason as fast as you can.

This is also possible that someone in ur room locked his soln and passed ur code to his friend.

    That's not the case, almost all solutions for this problem are similar.

    I think deactivating plagiarism detector for Div.2A problems is good idea, because mostly their solution codes are small and there can be collisions like that (although this one is really weird). What do you think about that? MikeMirzayanov

Hi. It seems this time I was inaccurate validating automated tools. I'll revert it tomorrow. I apologize for the inconvenience.
