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 product
  implicit none
  integer :: a, b
  read(*,*) a, b
  if (mod(a,2) == 0 .or. mod(b,2) == 0) then
     write(*,'(a)') "Even"
  else
     write(*,'(a)') "Odd"
  end if
  stop
end program product
