Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

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