多校联合第八场hdu5387Clock 最大公约数

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.

做多校的题都20道了，头一次自己过了一个，太激动了！！即使是水到不行，AC率过半 WA了几次 都错哪里了呢？

1.貌似fabs取绝对值的那个函数还是自己写比较好 C++就CE了

2.改程序的时候想起来了超过180度用360减 但是为什么没注意到超过12点得减去12呢 想到减去12了 为什么脑袋短路写成>12呢 →_→
