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

There are 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

0 0 0 
180 180 0 
1391/24 1379/24 1/2 
100 140 120 
Hint
每行输出数据末尾均应带有空格
