@chaman9 size of N can be up to 100 and you cannot store factorial of 100 in long long int.so you cannot use basic factorial technique here to find the factorial.you have to come up with technique in which you can store factorial of 100.(hint: use an array to store all the digits of your answer).

@chaman9 implementing these with vector may get complicated ,array will be better.
