using System;
class Program
    {
        static void Main(string[] args)
        {
            int a = int.Parse(Console.ReadLine());
            int b = int.Parse(Console.ReadLine());

            if (a * b % 2 == 1)
                Console.WriteLine("Odd");
            else
                Console.WriteLine("Even");
        }
    }
