Problem Statement

AtCoDeer the deer found two positive integers, a and b.
Determine whether the product of a and b is even or odd.

Constraints

1 ≤ a,b ≤ 10000

a and b are integers.

Input

Input is given from Standard Input in the following format:

a b

Output

If the product is odd, print Odd; if it is even, print Even.

Sample Input 1

3 4

Sample Output 1

Even

As 3 × 4 = 12 is even, print Even.

Sample Input 2

1 21

Sample Output 2

Odd

As 1 × 21 = 21 is odd, print Odd.

Solution in Haskell (GHC 7.10.3) (judge verdict: Wrong Answer)

module Main where

import Control.Applicative

evenOrOdd :: Integer -> Integer -> Bool
evenOrOdd a b = even (a * b)

main :: IO ()
main = do
    [a,b] <- map read . words <$> getLine
    if evenOrOdd a b then
        putStrLn "even"
    else
        putStrLn "odd"
