Angle Between Hands of a Clock

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
Output: 75

Example 3:

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

Example 4:

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.

class Solution {
    public double angleClock(int hour, int minutes) {
        double min = minutes / 60.0;
        double h = (hour / 12.0) + (1.0 / 12.0) * (min);
        double diff = Math.abs(h - min);
        diff = Math.min(diff, 1.0 - diff);
        double angle = diff * 360;
        return angle;
    }
