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: Runtime Error)

program ABC_086_A_Product 
   implicit none
   integer a, b
   write(*, '(a)', advance = 'no')'input a : '
   read(*, *) a
   write(*, '(a)', advance = 'no')'input b : '
   read(*, *) b
   if( mod(a*b, 2) == 0 ) then
      write(*, *)'Even'
   else if( mod(a*b, 2) == 1 ) then
      write(*, *)'Odd'
   end if
end program ABC_086_A_Product
