Problem 56288. Angle Between Analog Clock Hands

Given a datetime variable t, return the angle (in degrees) between the hour and minute hands of an analog clock at the time represented by t.
  • The angle returned should be the smaller of the two angles between the hands (ie it should always be in the range [0,180]).
  • Assume the hands are moving continuously (so at 03:30:00, the hour hand will be halfway between 3 and 4; at 03:26:30, the minute hand will be halfway between 26 and 27, etc).
  • The time may be am or pm; the angle returned should be assuming a standard 12-hour clock (so 03:26:30 and 15:26:30 will return the same angle).
