Leetcode Problem 1010. Pairs of Songs With Total Durations Divisible by 60

1010. Pairs of Songs With Total Durations Divisible by 60

Leetcode Solutions

Initialize an array remainders of size 60 to zero, which will hold the frequency of each remainder.
Initialize a variable count to zero, which will hold the number of valid pairs.
Loop through each song duration in the time array. a. Calculate the remainder of the current song duration divided by 60. b. If the remainder is 0, increment count by the frequency of 0 in remainders (since a pair of zeros will sum to 60). c. Otherwise, increment count by the frequency of the complement remainder (60 - current remainder). d. Increment the frequency of the current remainder in remainders.
Return the value of count.
