using System;
using static System.Console;
public class Hello{
    public static void Main(){
        string[] a = ReadLine().Split(' ');
        int x = int.Parse(a[0]);
        int y = int.Parse(a[1]);
        if(x%2==1&&y%2==1){
            WriteLine("Odd");
        }else{
            WriteLine("Even");
        }
    }
