Difficulty—

You are given positive integers $A$ and $B$. If $A$ is a divisor of $B$, print $A + B$; otherwise, print $B - A$. ## Constraints * All values in input are integers. * $1 \leq A \leq B \leq 20$ ## Input Input is given from Standard Input in the following format: $A$ $B$ [samples]

Samples

Input #1

4 12

Output #1

16

As $4$ is a divisor of $12$, $4 + 12 = 16$ should be printed.

Input #2

8 20

Output #2

Input #3

1 1

Output #3

2

$1$ is a divisor of $1$.
