Timer
Timer - a clock that can emit a sound signal after a specified period. Write a program to determine when the sound signal should be emitted.
Input
The first line of the input file provides the current time in the format HH:MM:SS, with leading zeros. The constraints are: HH ranges from 00 to 23, and both MM and SS range from 00 to 60.
The second line specifies the time interval to be measured, formatted as H:M:S. Here, H, M, and S range from 0 to 10^9, without leading zeros. If H=0 (or both H=0 and M=0), they can be omitted. For instance, 100:60 means 100 minutes and 60 seconds, equivalent to 101:0 or 1:41:0. Similarly, 42 represents 42 seconds. 100:100:100 denotes 100 hours, 100 minutes, and 100 seconds, which is the same as 101:41:40.
Output
Output the time in the format HH:MM:SS when the sound signal will be emitted. If the signal is emitted on a day other than the current one, append "+ <number> days" to the record. For example, if the signal is emitted the next day, output +1 days.
