Solution in C# (judge verdict: Wrong Answer)

using System;
class ITP1_1
{
    static void Main(string[] args)
    {
        //var exStdIn = new System.IO.StreamReader("stdin.txt");
        //System.Console.SetIn(exStdIn);

        int[] a = Array.ConvertAll(Console.ReadLine().Split(' '), new Converter<String, int>(s => int.Parse(s)));

        Console.WriteLine( 2*(a[0]+a[1]) );
    }
}
