Posted 2020-11-25 wentiliangkaihua

Given two numbers, hour and minutes. Return the smaller angle (in sexagesimal units) 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 temp = minutes / 60.0 * 360 - (hour % 12 * 30) - minutes / 60.0 * 30;
        return Math.min(Math.abs(temp),360 -  Math.abs(temp));
    }
}
