First of all, the answer is not $$$^{N}C_M$$$ as you think. You might want to think again or check the editorial.
Secondly, factorial grows faster than exponential, so it won't fit the integer limit or even long long after a small n. The submission shows the exception and the line number so you can try replacing the int by long long but I'm pretty sure it still won't help.
