Calculate the difference of angles between Hour hand and Minute hand of clock
E.g.
1) At 12:00 Angle Difference = 0 degrees
2) At 14:00 Angle Difference = 60 degrees
3) At 24:00 Angle Difference = 0 degrees
This is a slightly different, and easier, version of these problems:

Please note that the angle between the hour and minute hands also depends on the second hand. You assumed the zero-second in all test cases, which makes your problem a special case of an existing problem: http://www.mathworks.com/matlabcentral/cody/problems/392-clock-hand-angle-1
