Dear MikeMirzayanov,
I recieved the following email after the latest division 3 competiton:
Attention!
Your solution 282295673 for the problem 2014D significantly coincides with solutions AsianMario/282295673, GesusM/282321962. 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.
I do not know the user GesusM, this issue arises from Problem D of the CodeForces 974 (Div. 3) competition. I did use GeekForGeeks to help me with this article in particular: https://www.geeksforgeeks.org/maximum-number-of-overlapping-intervals/
After reviewing the submissions I feel that these similarities come from a common solution to a relatively straightforward problem. Hopefully this issue can be solved please do contact me for any lore clarification
Sincerely, AsianMario
