Statement
You are given a list of songs, where the duration of each song is represented by an integer array time, where time[i] indicates the length of the
Your task is to find and return the number of pairs of songs (i, j) such that:
i < j(i.e., the pair should consist of two distinct songs)The sum of their durations is divisible by 60, i.e.,
(time[i] + time[j]) % 60 == 0.
