Easy Accuracy: 17.75% Submissions: 62 Points: 2

Given string s of digits “0-9”, the task is to find the number of substrings which are divisible by 8 but not by 3.

Example 1:

Input: s = "888"
Output: 5
Explanation: Substring indexes : 
(0, 0), (0, 1), (1, 1), (1, 2), (2, 2).
Example 2:
Input: s = "083"
Output: 2
Explanation: Substring indexes :
(1, 1), (0, 1)

Your Task:  
You don't need to read input or print anything. Complete the function countDivisibleSubstring() which takes s input parameter and returns the integer value

Expected Time Complexity: O(|s|)
Expected Auxiliary Space: O(|s|)

Constraints:
1 ≤ |s| ≤ 106
