        static void Main(string[] args)
        {
            int counttabs = int.Parse(Console.ReadLine());
            double salary = double.Parse(Console.ReadLine());

            //double restsalary = 0;

            for (int n = 0; n <= counttabs; n++)
            {
                string website = Console.ReadLine();

                
                        switch (website)
