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.

1 21

Sample Output 2

Odd

As 1 × 21 = 21 is odd, print Odd.

Solution in Fortran (GNU Fortran 9.2.1) (judge verdict: Accepted)

program main 
    integer :: a, b 

    read(*,*) a, b 

    if (mod(a,2).ne.0 .and. mod(b,2).ne.0) then 
        write(*,*) 'Odd'
    else 
        write(*,*) 'Even'
    end if 
end program
