MikeMirzayanov I have been consistent on your platform for last 6 months. I was starting to get along the way with CP. But after today's contest I received a mail stating that my solution coincides with some other solutions. I have PERSONALLY CHECKED all the sent solution and found my solution quite different from other. Yes approach may be similar as it was a trivial problem and many have solved something like that previously.

Please don't kill my motivation for CP. If It is possible have one human verification.
