Given two numbers, `hour` and `minutes`, return the smaller angle (in degrees) formed between the `hour` and the `minute` hand.

Answers within `10-5` of the actual value will be accepted as correct.

Example 1:

    Input: hour = 12, minutes = 30
    Output: 165

Example 2:

    Input: hour = 3, minutes = 30
    Output: 75

Example 3:

    Input: hour = 3, minutes = 15
    Output: 7.5

Constraints:

- `1 <= hour <= 12`
- `0 <= minutes <= 59`
