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.

**Your Task:**

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(10^{5})

**Constraints:**

1<=N,A[i]<=10^{5}
