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 1 × 21 = 21 is odd, print Odd.

Solution in Common Lisp (SBCL 1.1.14) (judge verdict: Accepted)

(defun main()
    (let* ((a (read))
           (b (read)))
        (format t "~A~%" 
            (if (zerop (rem (* a b) 2)) "Even" "Odd"))))

(main)
