{
    internal class Program
    {
        static void Main(string[] args)

namespace CSharp
{
    internal class Program
    {
        static void Main(string[] args)

namespace CSharp
{
    internal class Program
    {
        static void Main(string[] args)

namespace CSharp
{
    internal class Program
    {
        static void Main(string[] args)
