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

int main(){
  
  int a,b,c;
  
  do{
    scanf("%d %d",&a,&b);
  }while(a<1||b>10000);

  c = a*b;

  if(c%2==0)
    printf("Even");
  else
    printf("odd");
  
  return 0;
