public static class Program
{
  public static void Main(string[] args)
  {
     string[] input = System.Console.ReadLine().Split(' ');
     int a = int.Parse(input[0]);
     int b = int.Parse(input[1]);
     string answer = ((a % 2 == 0) || (b % 2 == 0))
       ? "Even"
       : "Odd";
     System.Console.WriteLine(answer);
  }
}
