Clock angle problem

On a 12-hour analog clock, given time as integers h and m, return the smaller angle between the hour and minute hands in degrees.

Input

h: hour in 0–23 (treat 13 as 1, 0 and 12 are the same)

m: minute in 0–59

Output

Floating-point degrees, up to two decimals, in [0, 180]

Requirements

O(1) time, O(1) space

Handle edge cases like 0:00, 12:00, 23:59

If the smaller and larger angles are equal, return 180
