Given an array A containing N integers.Find out how many elements should be added such that all elements between the maximum and minimum of the array is present in the array.
Input: N=5 A=[205,173,102,324,957] Output: 851 Explanation: The maximum and minimum of given array is 957 and 102 respectively.We need to add 854 elements out of which 3 are already present.So answer is 851.
Input: N=1 A= Output: 0 Explanation: We don't need to add any element to the array.
You don't need to read input or print anything. Your Task is to complete the function countElements() which takes an integer N and an array A of size N and returns the number of elements needed to be added to the array so, that all elements between the minimum and maximum of the array are present.
Expected Time Complexity:O(N)
Expected Auxillary Space:O(105)
