Find The Minimum time difference
Minimum time difference
Given a list of 24-hour clock time points in "HH:MM" format. Write a program to find the minimum minutes difference between any two time-points in the list.
Given hours: [00:00, 03:00, 22:30] minimum time difference: 90 Given hours: [01:59, 03:00, 21:50, 22:30] minimum time difference: 40
- Convert all the given times to minutes and have these stored in a list.
- Now sort the minutes list in ascending order.
- Now get the difference between every consecutive time and keep track of the minimum.
- To cover the edge case when one time is before and after the 24:00 hours, in that case add 1440 (there are 1440 minutes in 24 hours ) to time which is before 24:00. For example if the first time is 1:00 and the second time is 23:30. So minutes are 60 and 1410 respectively. Now add 1440 to 60 which becomes 1500. Now the difference is 1500-1410 = 90 mins.
- Return the minimum difference.
- See the code below for more understanding.
Given hours: [01:59, 03:00, 21:50, 22:30] minimum time difference: 40
