            Console.WriteLine("Enter the range: ");
            r = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("FLOYD'S TRIANGLE");
            for (i = 1; i <= r; i++)
            {
                for (j = 1; j <= i; j++, k++)
                Console.Write(k+"\t");
                Console.WriteLine("\n");
