1010 - Pairs of Songs With Total Durations Divisible by 60\. Medium You are given a list of songs where the ith song has a duration of `time[i]` seconds. Return _the number of pairs of songs for which their total duration in seconds is divisible by_ `60`. Formally, we want the number of indices `i`, `j` such that `i < j` with `(time[i] + time[j]) % 60 == 0`. **Example 1:** **Input:** time = [30,20,150,100,40] **Output:** 3 **Explanation:** Three pairs have a total duration divisible by 60: (time[0] = 30, time[2] = 150): total duration 180 (time[1] = 20, time[3] = 100): total duration 120 (time[1] = 20, time[4] = 40): total duration 60 **Example 2:** **Input:** time = [60,60,60] **Output:** 3 **Explanation:** All three pairs have a total duration of 120, which is divisible by 60. **Constraints:** * 1 <= time.length <= 6 * 104 * `1 <= time[i] <= 500`
