题目描述
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
SAMPLE INPUT
2
12 30
06 00
SAMPLE OUTPUT
165
180
Explanation
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.
