Clock angle problem

/*

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
