Lukas spends the day of New Year's Eve counting the minutes that are missing so that they give the grapes. Can help him?

Input

The entry consists of a series of hours, each in a line. Each hour is formed by the hours and minutes separated by two dots ( : ) and always using two digits. A representation is used in 24 hours format (that is, from 00:00 to 23:59).

 

Entry ends when the time is midnight (00:00), which should not be processed.

For each test case a line will be shown with the number of minutes remaining by midnight.
