Hey Shubham, this library is not supported by the ide, so instead of using this use other standard libraries and for that you can use#include <bits/stdc++.h> . In C++ It is basically a header file that includes every standard library.

it still showing error ,can u correct it and show to me

Yes sure, you can check this out.

the changes u made,now its not working for larger input,thats why any of test case of mine didnt pass

Hey Shubham, for calculating the factorial of large numbers you are supposed to use dynamic programming otherwise it will give TLE.
