Example to solve recursion problemsThe below program gives an illustration of finding the factorial of a number using recursion in C.#include <stdio.h> unsigned long long int factorial(unsigned int i) { if(i<= 1) { return 1; } return i * factorial(i - 1); } int main() { int i...

Here's a little challenge, use recursion to write a program that returns the factorial of any number greater than 0. (Factorial is number * (number - 1) * (number - 2) ... * 1). Hint: Recursively find the factorial of the smaller numbers first, i.e., it takes a number, ...
