Solution: Pairs of Songs With Total Durations Divisible by 60
Explore how to identify pairs of song durations that add up to a multiple of 60 by tracking remainders in an array. Learn to implement an O(n) time and O(1) space complexity solution that efficiently counts valid pairs, preparing you to solve similar coding interview problems in C#.

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.
