Incomplete Array
Easy Accuracy: 40.41% Submissions: 626 Points: 2

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.

Example 1:

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.

Example 2:

Input:
N=1
A=[545]
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)

Constraints:
1<=N,A[i]<=105
