Given a sorted array of size N. Count the number of distinct absolute values present in the array.
Example 1:
Input:
N = 6
Arr[] = {-3, -2, 0, 3, 4, 5}
Output: 5
Explanation: There are 5 distinct absolute
values 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. Your task is to complete the function distinctCount() which takes the array of integers arr[] and its size n as input parameters and returns an integer denoting the answer.
Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)
Constraints:
1 <= N <= 105
-108 <= Arr[i] <= 108
The array may contain duplicates
