Program- Write an iterative version and a recursive version of function OCCURS that determines how many times an integer value x occurs in array a[0..na-1].
Q- Write a main program that illustrates the work of your functions. E.g., if a[ ]={1,2,3,3,4,5} then 3 occurs 2 times and 7 occurs 0 times.
Determines how many times an integer value occurs in array and prepare an iterative version and a recursive version of function.
