I got a message regarding plagiarism in one of my solutions (matching with hihihizaru) in the last contest. Due to this last contest is unrated for me. But I solved all the questions by myself. Can anyone help me in this situation? How can I claim back my solutions?

My submission: 160882443

hihihizaru's submission: 160869037

See the details:

Your solution 160882443 for the problem 1694D significantly coincides with solutions hihihizaru/160869037, fake_1100/160882443. 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. In case of repeated violations, your account may be blocked.
