Question 3:
Santa commutes to post office each day to send out reply letters to the kids. If there is no rush-hour traffic, his commute time is 2 hours. However, there is often rush-hour traffic. Specifically, rush-hour traffic occurs from 07:00 (7am) until 10:00 (10am) in the morning and 15:00 (3pm) until 19:00 (7pm) in the afternoon. During rush-hour traffic, his speed is reduced by half.

Santa leaves either on the hour (at XX:00), 20 minutes past the hour (at XX:20), or 40 minutes past the hour (at XX:40).

Given Santa’s departure time, at what time does he arrive at post office?

Input Specification
The input will be one line, which contains an expression of the form HH:MM, where HH is one of the 24 starting hours (00, 01, : : :, 23) and MM is one of the three possible departure minute times (00, 20, 40).
