Revision en1, by Duelist1234, 2024-04-22 16:50:40

In yesterdays Div 2 C a part of the solution required to divide factorials. Know you might think that that is easy , but ofcourse , there was just one thing screwing everything up , mod 10^9+7. Just one number ruined everything. And thats why im asking , how to divide factorials properly when you take their mod first?
