Every school morning Mirko is woken up by the sound of his alarm clock. Since he is a bit forgetful, quite often he leaves the alarm on on Saturday morning too. That’s not too bad tough, since he feels good when he realizes he doesn’t have to get up from his warm and cozy bed.

He likes that so much, that he would like to experience that on other days of the week too! His friend Slavko offered this simple solution: set his alarm clock 45 minutes early, and he can enjoy the comfort of his bed, fully awake, for 45 minutes each day.

Mirko decided to heed his advice, however his alarm clock uses 24-hour notation and he has issues with adjusting the time. Help Mirko and write a program that will take one time stamp, in 24-hour notation, and print out a new time stamp, 45 minutes earlier, also in 24-hour notation.

If you are unfamiliar with 24-hour time notation yourself, you might be interested to know it starts with 0:00 (midnight) and ends with 23:59 (one minute before midnight).

Your Program

Write a program which asks the user for two integers:

  1. The hour of the day that Mirko needs to get out of bed.
  2. The minute of the day that Mirko needs to get out of bed.

You may assume that the user will only enter positive integers for each input. Further, you may assume that the hours will be no greater than 23, and the minutes will be no greater than 59.

Then, you program should determine when Mirko needs to set his alarm and output the time (hours, then minutes, seperated by a space) on a single line.

Example Interaction 1

Hours: 10
Minutes: 10
9 25

Example Interaction 2

Hours: 0
Minutes: 30
23 45

Example Interaction 3

Hours: 23
Minutes: 40
22 55
