Attention!

Your solution 160110157 for the problem 1689B significantly coincides with solutions it_abhishek/160108936, kautilya101001/160110157. 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.me/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 believe this is clearly a coincidence that my solution coincides with solution it_abhishek/160108936. Plus i have done my first submission before him which i rebuild due to silly mistakes to successfully submit it. This is a coincidence cause same logic has been used by many users.
