In Subodh's CS Deparment there is a contest of Geometry. In this contest students are told to find minimum angle between hour and minute hand.
Input:
The first line contains the number of test cases, T. T lines follow, each of which contains two integer Hour hand H and minute hand M .
Output:
Print the minimum angle between the hands.
Constraints
1<=T<=100
01<=H<=12
01<=M<=59
In first input time is 12:30 i.e. hour hand is in middle of 12 and 1 & minute hand is pointing at 6 which makes angle of 165 degrees.
In Second input time is 06:00 i.e. hour hand is at 12 and minute hand is at 6 which makes angle of 180 degrees.
