How many times does the minute hand and the hour hand intersect each other in the given time ?
First line contains the number of test cases t. Each test case has two lines representing the start time and end time respectively. The time would be in format (hh:mm). hh will be between 00 and 23, mm will be between 00 and 59. If the minute and hour hand are overlapping right at the start time (like at 12:00) then it would not be counted. However, intersection at end time is counted .
(00:00 <= 'start time' < 'end time' <= 23:59).
For each test case print, on a separate line, the number of times they overlap each other.
