One day Mirko was cleaning up his room and found a straightedge and a
compass. He went to the school the next day and challenged his friend Slavko
to a geometric construction battle. Mirko knows how to construct some angles
using the straightedge and compass and knows how to subtract and add any
two angels he constructs. Slavko now shouts random angles and Mirko must
draw them as fast as possible.
You are observing this battle and would like to know if Mirko can construct the
angles Slavko shouts at all.
Input
The first line of input contains two integers, `N` (`1\ ≤\ N\ ≤\ 10`), number of angles
Mirko knows how to construct initially and `K` (`1\ ≤\ K\ ≤\ 10`), number of angles
Slavko selected.
The second line of input contains `N` integers, all smaller than 360, the angles
Mirko knows how to construct initially.
The third line contains `K` integers, all smaller than 360, the angles Slavko
selected.
Output
Output consist of `K` lines, one for each angle Slavko selected. The `i`-th line
should contain "YES" if Mirko can construct the `i`-th angle, and "NO" otherwise.

First example description:
Subtracting 30° from 70° yields 70° – 30° = 40°.
Second example description:
Adding 100° 15 times yields 1500°, also known as 60°.
