What will be the output of the following C# code?

static void Main(string[] args)
{
    int i, s = 0, a = 1, d;
    i = Convert.ToInt32(Console.ReadLine());
    do
    {
        d = i % (2 * 4);
        s = s + d * a;
    }while ((Convert.ToInt32(i = i / (2 * 4))) != 0 
     && (Convert.ToBoolean(Convert.ToInt32((a) = (a * 10)))));
    Console.WriteLine(s);
    Console.ReadLine();
}
enter i = 342.
