Problem type
Alert, Nunavut

After a particularly bad ice storm, the central clock from the little town of Alert, Nunavut has frozen, and the hands no longer move.

Since the clock stopped, the locals have been using a stopwatch to determine the current time by adding the stopwatch's current time N (in minutes) with that of the clock. However, adding is a job for computers, so until the clock thaws, they've asked you to help them determine the current time!

Input Specification

The first line of input will contain the space-separated integers H (0 \le H \le 24) and M (0 \le M \le 60). These integers represent the hour and minutes at which the clock stopped, respectively.
The second line of input will contain the integer N (1 \le N \le 10^9).

Output Specification

Output the current time in 24-hour format, with the hours and minutes separated by a space.

    The test cases used for this problem involve putting in the time not in the correct 24-hour format.

    Ex: It will test the time "24 12", or "24 45".

    I know my code isn't the most sophisticated but it's still giving me the correct answers, no matter what I try. Yet I get WA on the 40th and 54th questions. Help?

    EDIT: Well I managed to solve the question properly, and only 4 minutes after my contest time ended. However, I would still like to know what the test cases were that I kept getting wrong.

      Some input seem to be out of bounds, on one testcase there was H = 24

    Methinks that 100 test cases is slightly excessive, but who knows?

    It is possible to understand the question by looking at the Sample Inputs but, from the problem statement I dont know what I am suppose to do and I dont know what H, M and N are. Some clarifications might be helpful. Thanks.

      I've clarified the problem statement (it was an oversight).

      H and M represent the stop time in 24-hour format, and N represents the minutes counted by the stopwatch.
