Здарвейте, колеги имам нужда от помощ за следната задача №7 от домашното "salary":Това ми е кода:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace salary
{
    class Program
    {
        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)
                        {

case "Facebook":

salary = salary - 150;
break;

case "Instagram":

salary = salary - 100;
break;

case "Reddit":

                                salary = salary - 50;
                                break;
                        }

                    }
                  if (salary<=0)
                  {
                      Console.WriteLine("You have lost your salary.");
                  }
                  else
                  {
                      Console.WriteLine(salary);
                  }
                }
            }
        }

using System;

namespace Salary
{
    class Program
    {
        static void Main(string[] args)
        {
            int n = int.Parse(Console.ReadLine());
            int salary = int.Parse(Console.ReadLine());
            int facebook = 150;
            int instagram = 100;
            int reddit = 50;

            for (int i = 1; i <= n; i++)
            {
                string page = Console.ReadLine();
                if (page == "Facebook")
                {
                    salary -= facebook;
                }
                else if (page == "Instagram")
                {
                    salary -= instagram;
                }
                else if (page == "Reddit")
                {
                    salary -= reddit;
                }
                else
                {
                    salary -= 0;
                }
            }
            if (salary <= 0)
            { Console.WriteLine("You have lost your salary."); }

else

{ Console.WriteLine($"{salary}"); }

}
}
