⚡ Question

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. Hide Hint #1
The tricky part is determining how the minute hand affects the position of the hour hand. Hide Hint #2
Calculate the angles separately then find the difference.

🍑 Solution

class Solution {
    public double angleClock(int hour, int minutes) {
        double h,m,a,x;
        if(hour==12){
            hour=0;
            if(minutes==60){
                minutes=0;
                hour+=1;
            }
        }
        h=(0.5 * (hour*60 + minutes)); 
        m=minutes*6;
        x=Math.abs(h-m);
        a=Math.min(360-x,x);
        return a;
    }
}
