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 1 × 21 = 21 is odd, print Odd.

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>

int
main(){
  int a, b;
  scanf("%d %d", &a, &b);
  if(a < 1 || 10000 < b)
    return 1;

  if( (a % 2) && (b % 2)  ){
    printf("Odd\n");
  } else {
    printf("Even\n");
  }
  
  return 0;
}
