"Attention!
Your solution 294553610 for the problem 2047B significantly coincides with solutions deepakgoswami0552/294546629, rahul_ghosh/294553610, mariemcharef42/294554047, AdariKarthikeya/294559658, amld/294560803, vedant.nagar21/294562313, Shiv_Kamate/294564614, dineshdumka874/294566697, Fiaze_SHU/294568824, code_RN/294568935, pradyuman554/294572529, Tanvi_2765/294575212, tracktor/294575276, shettyaastha/294581174. 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://mirror.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 get this message today. But i solve the problem first. I check some random submission time of some of the others and find that i solved the problem first . And i do not know them, i did not share my code to anyone .So it is very disappointing for me. It is my humble request to codeforce community to recheck the problem and do not give me such penalty please. here i added my submission time screenshot please recheck it with others accepted code submission time please .
