Median Function lo statistics, when a set of values is sorted in ascending or descending order its median is the middle Value for odd number of values). If the set contains an even number of values the median is the average of the two middle values. Write a function that accept arguments the following 1. An array of integer 2. An integer that indicates the number at elements in the array The function should determine the median of the array This value should be retumed as a double (Assume the values in the array are already sorted) Demonstrate your pointer prowess by using pointer notation instead of array notation in this function
