Problem type

A popular meme that's been going around on the internet goes like this:

If you start <some something> at <some time> on <some day>, then you'll be able to <some other thing> as the clock strikes midnight. Kick off 2018 the right way.

Given that this certain "some something" takes $h$ ~h~ hours, $m$ ~m~ minutes, and $s$ ~s~ seconds, find this certain "some time".

Constraints

$0 \le h,m,s \le 10^9$ ~0 \le h,m,s \le 10^9~

Input Specification

Three space-separated integers, $h$ ~h~, $m$ ~m~, and $s$ ~s~, respectively.

Output Specification

The time of day when you should start the task, in the form hours:minutes:seconds. Note that this time should follow the 12-hour clock convention, with all leading zeroes, including the hours. You should not print out am or pm though.

EDIT: If the time is 12:??:??, you should output 00:??:??.

Sample Input 1

0 34 5

Sample Output 1

11:25:55

Sample Input 2

0 120 0

Sample Output 2

10:00:00

Sample Input 3

When the time needed to perform the task is converted to seconds the value may exceed $2^{31}-1$ ~2^{31}-1~ so it cannot be stored as an int.
