Calculate the angle between the hour hand and minute hand.

**Note: **There can be two angles between hands; we need to print a minimum of two. Also, we need to print the **floor** of the final result angle. For example, if the final angle is 10.61, we need to print 10**.**

**Example 1:**

Input:H =9 ,M =0Output:90Explanation:The minimum angle between hour and minute hand when the time is 9 is 90 degress.

**Example 2:**

Input:H =3 ,M =30Output:75Explanation:The minimum angle between hour and minute hand when the time is 3:30 is 75 degress.

**Your Task:**

You don't need to read, input, or print anything. Your task is to complete the function **getAngle(),** which takes 2 Integers H and M as input and returns the answer.

**Expected Time Complexity:** O(1)

**Expected Auxiliary Space:** O(1)

**Constraints:**

1 ≤ H ≤ 12

0 ≤ M < 60

H and M are Integers
