Problem 1 (8 points) The mathematical definition and example of a recursive function f is as follows: ase case f(o) 5 ive case le 1) 2(f (n- 1)) 3-2 0) - 3- 2(5)-3-7 Consider the following function prototype for calculating f (n) int f(int n) In a C++program named recursion.cpp, complete the function prototype using recursion. For full credit, the program must include the follow ing: A true recursive structure (including recursive function calls) . Display on console output for each iteration of the factorial calculation, including f (0) and f (n) .A comment indicating the base case of the function .A comment indicating the recursive case of the function Input validation in the main function for integers greater than or equal to 0 A sample run of the program is shown below: Enter a number greater than or equal to 0: -1 Please enter a valid number! Enter a number greater than or equal to 0: 8 f (0): 5 f (1) 7 f (2) 11 f (3): 19 f (4) 35 f (5) 67 (6 131 f (7) 259 f (8) 515 Press any key to continue
