practice.

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

    }
    public T pop()
    {
        T obj = stk.Pop();
        return obj;
    }
}
class Program
{
    static void Main(string[] args)
    {
        Generic<string> g = new Generic<string>();
        g.push(40);
        Console.WriteLine(g.pop());
        Console.ReadLine();
    }
}
