Svala has been waiting for forever and the wait barely shortens, it seems. She looked at the clock quite a while ago so she’s going to check what the time is. Svala doesn’t know how to read the time off a clock though, can you help her and tell her how many minutes have passed since she first looked at the time?
Input
The input consists of two lines, both in the format $HH:MM$. The first line shows what the time was when Svala first looked at the clock. The second line shows what the time is now.
Output
Print one line with a single integer, the number of minutes Svala has waited. She will never wait for $24$ hours or more.
