    {
        add<int> sum = Sum;
        Console.WriteLine(sum(10, 20));

        add<string> con = Concat;
        Console.WriteLine(con("Hello ","World!!"));
    }

    public static int Sum(int val1, int val2)
    {
        return val1 + val2;
    }

    public static string Concat(string str1, string str2)
    {
