Absolute distinct count
Basic Accuracy: 31.57% Submissions: 38 Points: 1

Given a sorted array of N integers, find the number of distinct absolute values among the elements of the array. 

Example 1:

Input:
N = 6
arr[] = {-3, -2, 0, 3, 4, 5}
Output: 5
Explanation: There are 5 distinct absolute 
values among the elements of this array, 
i.e. 0, 2, 3, 4 and 5.


Example 2:

Input:
N = 9
arr[] = {-1, -1, -1, -1, 0, 1, 1, 1, 1}
Output: 2
Explanation: There are 2 distinct absolute values 
among the elements of this array, i.e. 0 and 1.


Your Task:
You don't need to read input or print anything. Complete the function distinctCount() which takes the array of integers arr[] and its size as input parameters and returns the number of distinct absolute values.


Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)


Constraints:
1 ≤ N ≤ 105
0 ≤ |Arr[i]| ≤ 106
