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 Fortran (gfortran v4.8.4) (judge verdict: Accepted)

program main
  implicit double precision (a-h, o-z)
  read(*, *) i, j
  k = ibits(i, 0, 1) * ibits(j, 0, 1)
  if (k == 0) then
    write(*, *) "Even"
  else
    write(*, *) "Odd"
  endif
  stop
end program main
