Given n size unsorted array, find its mean and median. Mean of an array = (sum of all elements) / (number of elements) Median of a sorted array of size n is defined as below: It is middle element when n is odd and average of middle two elements when n is even. Since the array is not sorted here, we sort the array first, then apply above formula. Examples: Input : a[] = {1, 3, 4, 2, 6, 5, 8, 7} Output Mean = 4.5 Median = 4.5 Sum of the elements is 1 + 3 + 4 + 2 + 6 + 587 = 36 Mean 36/8 = 4.5 Since numbers of elements are even, median is average of 4th and 5th largest elements. which means (4 +5)/2 = 4.5 Input : a[] == {4, 4, 4, 4, 4} Output Mean = 4 Median = 4
