    3185 - Count Pairs That Form a Complete Day II\.

    Medium

    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:

    • <code>1 <= hours.length <= 5 * 10<sup>5</sup></code>

    • <code>1 <= hoursi<= 10<sup>9</sup></code>
