Count Pairs That Form a Complete Day I
Given an integer array hours representing times in hours, return an integer denoting the number of pairs i, j where i < j and hours[i] + hours[j] forms a complete day.
Given an integer array hours representing times in hours, return an integer denoting the number of pairs i, j where i < j and hours[i] + hours[j] forms a complete day.
A complete day is defined as a time duration that is an exact multiple of 24 hours.
For example, 1 day is 24 hours, 2 days is 48 hours, 3 days is 72 hours, and so on.
Example 1
Input: hours = [12,12,30,24,24]
Output: 2
Explanation: The pairs of indices that form a complete day are (0, 1) and (3, 4) .
Example 2
Input: hours = [72,48,24,3]
Output: 3
Explanation: The pairs of indices that form a complete day are (0, 1) , (0, 2) , and (1, 2) .
Constraints
- 1 <= hours.length <= 100
- 1 <= hours[i] <= 10^9
