In statistics, the mode of a set of values is the value that occurs most often or with the greatest frequency. write a function that accepts as arguments the following: an array of integers an integer that indicates the number of element in the array. the function should determine the mode of the array. that is, it should determine which value occurs most often. the mode is the value of the function should. if the array has no mode (none of the values occur more than once), the function 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.
