254 Description: Note this assignment is to be done individually The Recursion Assignment: You will implement and test four short recursive functions. With the proper use of recursion, none of these functions should require more than a few lines of code. Purposes: Ensure that you can write and test small recursive functions. Example: / This maps very naturally to a recursive C+ progran (in factoriali.cpp) include ciostrean> using namespace std int factorial(int n) // 1, 1, 2, 6. 24, 120, 720, .. if () return 1 return * factorial(n-1); int main() int n; cout
