Attention!

Your solution 270003845 for the problem 1992D significantly coincides with solutions lazyboi0001/269951234, mysojinyeast/269975714....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.

I am using my own template for very long time. I don't feel their code and my code is same. Can Anyone help me in that please.

I always used to add extra operations so that my code becomes unique My Submission is https://codeforces.com/contest/1992/submission/270003845 Please check this blog:MikeMirzayanov
