The regular cheater of codeforces Kaustov_584 has started cheating again. In today's Div 2 D problem this is his submission 117243132
He has also submitted problem B in the last minute which I am pretty sure he cheated in that too!
stopcheatingmyself has cheated in problem D too!
See his submission 117244766. He has copy pasted the bigint library from here Arpa's Big int library blog
If we remove that big int snippet we can easily see that both of them cheated. I am pretty sure they are not the only ones.
Thus I request MikeMirzayanov sir to take strict actions against these cheaters
They are just spoling the platform.
