Problem Description
Give a time.(hh:mm:ss),you should answer the angle between any two of the minute.hour.second hand
Notice that the answer must be not more 180 and not less than 0
Input
T
(1≤T≤104) test cases
for each case,one line include the time
0≤hh<24,
0≤mm<60,
0≤ss<60
Output
for each case,output there real number like A/B.(A and B are coprime).if it's an integer then just print it.describe the angle between hour and minute,hour and second hand,minute and second hand.
Sample Input
4
00:00:00
06:00:00
12:54:55
04:40:00
Sample Output
100 140 120
