Griffy has arrived at Don Mills, but he's too early and there's no one at the school to help him with his coding! He decides to wait until school starts so he can get some pointers (see what we did there?). Given the time he arrives at and the time that school starts, determine how many seconds Griffy will need to wait.
All times will be given in the format
HH:MM:SS ~(0 \le HH \le 23, 0 \le MM \le 59, 0 \le SS \le 59)~.
First line: Time Griffy arrives (time will be less than
Second line: Time school starts (time will be less than or equal to
Note: The time school starts will be strictly greater than the time Griffy arrives.
One line, the number of seconds Griffy will need to wait.
