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 1 × 21 = 21 is odd, print Odd.

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

int main()
{
  int a[4];
  int i = 0;
  while (i < 4)
  {
    scanf("%d ",&a[i]);
    //if (i % 2 == 0 && i != 0)
    i++;
  }
  if (a[0] % 2 == 0 || a[1] % 2 == 0)
    printf("Even");
  else
    printf("Odd");
}
