Donald is very hungry. He grabs a TV dinner, puts it in the microwave, and enters 02:15 to cook it for 2 minutes and 15 seconds. Unknown to Donald, microwave takes these values as hours and minutes, i.e., microwave takes 02:15 as 2 hours and 15 minutes (not 2 minutes and 15 seconds).

That is, we need to tell Donald that his food will cook 2 hours, 12 minutes, and 45 seconds more (longer) than what he was expecting!   The Problem:   Given the initial time in the form ofMM:SS, where the input is actually taken asHH:MM, determine how much extra the food will be in the microwave.
