1344. Included angle of clock pointer

1344. The angle between the hands of the clock

Here are two numbers for you hour and minutes . Please return to the clock , The angle of a small angle consisting of the hour hand and minute hand of a given time （60 The system of units ）.

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

The question is very simple , In fact, it just needs some mathematical knowledge , The solution code is as follows ：

double angleClock(int hour, int minutes){
    
    double x=hour*5+minutes/60.0*5;
    double y=minutes;
  

    return fmin(fabs(x-y)*6,(60.0-fabs(x-y))*6);
