Title:
Factorial program in C using recursion
Solved #1326
Description:
This program implements a function named factorial which computes the factorial of a number with a O(n) time complexity.
Why is this PR needed?
The other solutions does the job but they are not using recursion as clearly mentioned in the issues. My solution uses recursion and thus is maintaining the criteria of the issue.
My solution:
int factorial(int n) { if(n == 0) return 1; else return n * factorial(n-1); }
