Solution:

Given: Positive Integer, N
We need to find N!, it is also given that 1<=N<=10

It is important as for large numbers we will not be able to find the value of N! as it will require 100s of digit and we can't store such a huge number in C++ integers data type and due to overflow we will get the wrong answers.

In solution a = n.
