        static void Main(string[] args)
        {
            Console.WriteLine(test(53));
            Console.WriteLine(test(30));
            Console.WriteLine(test(51));
            Console.ReadLine();
        }

          public static int test(int n)
        {
            const int x = 51;

            if (n > x)
            {
                return (n - x)*3;
            }
            return x - n;
