Solution coincides but I think Problem A is trivial enough and the chances are higher of coincidence.

Attention!

Your solution 109231770 for problem 1493A significantly coincides with solutions JAMMY/109231770, singleLOOP/109233079. 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.net/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.

This has happened because problem A of DIV2 rounds is trivial most of the times and the code is of 4-5 lines so it is just a coincidence that someone wrote a similar thing which I did even if you would go through a number of other submissions you would find that the logic is nearly same and since it is a small code it gets matching for a number of people.
