Given a time (hours as $H$ and minutes as $M$), determine the smaller angle between the two hands of a clock showing the time and print it.

Input

The input will contain two integers: $H$ ($0 \le H < 12$) and $M$ ($0 \le M < 60$).

Output

Print the angle in degrees (positive and accurate to $10^{-4}$).

Sample

Input	Output
10 15	142.5000000

N.B.: It's better if you solve this by your own. Thank you!
