Problem Statement

You are given integers $A,B$.
Let $X$ be the number of common divisors of $A$ and $B$.
Determine whether $X$ is even or odd.

* A divisor shared by both $A$ and $B$ is called a common divisor of $A$ and $B$.

Constraints

• $A,B$ are integers
• $1 \le A,B \le 10^{18}$

Input

$A\ B$

$A$ and $B$ are given separated by a space.

Output

Print Even if $X$ is even, and Odd if it is odd.
Print a newline at the end.
