Q. Given two arrays of train arrival time and departure time and number of platform (int), you have to distrube traffic equally among all platform and return the traffic distribution.
arrival = [9:00, 9:40, 9:50, 11:00, 15:00, 18:00]
departure = [9:10, 12:00, 11:20, 11:30, 19:00, 20:00]
NoP (no. of platform) = 3

For example -
//This is wrong traffic distribution as it's not equally distributed
P1: T1, T3
P2: T5, T2, T4
P3:
//Right traffic distribution
P1: T1, T3
P2: T5, T2
P3: T4

The interviewer was not very co-operative and didn't get much hints. I was not able to come up with right solution on time, any suggestion please.
