I got this message from the system Attention!
Your solution 144520272 for the problem 1632A significantly coincides with solutions i_love_krishna/144520272. 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.
Neither I cheat nor I use ideone so please help.MikeMirzayanov
