Write a function that accepts as arguments the following: A) An array of integers B) An integer that indicates the number of elements in the array The function should determine the mode of the array. That is, it should determine which value in the array occurs most often. The mode is the value the function should return. If the array has no mode ( none of the values occur more than once), the func-tion should return - 1. ( Assume the array will always contain nonnegative values.) Demonstrate your pointer prowess by using pointer notation instead of array notation in this function.
