Day 370

[Birdy-C]

Good morning! Here's your coding interview problem for today.

This problem was asked by Postmates.

The “active time” of a courier is the time between the pickup and dropoff of a delivery. Given a set of data formatted like the following:

(delivery id, timestamp, pickup/dropoff)
Calculate the total active time in seconds. A courier can pick up multiple orders before dropping them off. The timestamp is in unix epoch seconds.

For example, if the input is the following:

(1, 1573280047, 'pickup')
(1, 1570320725, 'dropoff')
(2, 1570321092, 'pickup')
(3, 1570321212, 'pickup')
(3, 1570322352, 'dropoff')
(2, 1570323012, 'dropoff')
The total active time would be 1260 seconds.

Thanks for sending me the problem for Day 370 @Birdy-C . I believe the input in the problem statement isn't actually correct and definitely doesn't result in an answer of 1260 seconds.
