Description

It was the last day at Russia, after the World Finals has ended. Coach fegla was travelling back to Cairo on the same day but later. Coach Fegla was really tired, and he had to sleep before he headed to the Airport. Due to an unknown reason his phone alarm was not working, and he needed something to wake him up. Fortunately his stopwatch was just working fine, and it worked in count down mode, and it supported only minutes. You will be given the current time, and the time he wished to wake up, help him determine the number of needed minutes to configure the stopwatch properly.

Input

The first line will be the number of test cases T. The following T lines each will contain 4 integers hc mc hw mw which represent the current time(hours, and minutes), and the wake up time(hours, minutes). 1 ≤ T ≤ 100 0 ≤ hc, hw ≤ 23 0 ≤ mc, mw ≤ 59 Note that both times will be on the same day, and the wake up time comes after the current time. Assume the day starts at 00:00 and ends at 23:59.

Output

For each test case print a single line containing: Case_x:_y x is the case number starting from 1. y is the required answer. Replace underscores with spaces.

Sample Input

2 1 22 13 21 2 35 21 35

Sample Output

Case 1: 719 Case 2: 1140
