/***************************************************************************************
 * Given two numbers, hour and minutes. Return the smaller angle (in degrees) formed
 * between the hour and the minute hand.
 *
 * Example 1:
 *
 * Input: hour = 12, minutes = 30
 * Output: 165
 *
 * Example 2:
 *
 * Input: hour = 3, minutes = 30

 *
 * Input: hour = 4, minutes = 50
 * Output: 155
 *
 * Example 5:
 *
 * Input: hour = 12, minutes = 0
 * Output: 0
 *
 * Constraints:
 *
 * 1 <= hour <= 12
 * 0 <= minutes <= 59
 * Answers within 10^-5 of the actual value will be accepted as correct.
