    class Pattern

    {

        static void Main(string[] args)

        {

            Console.WriteLine("Program for displaying pattern of *.");

            Console.Write("Enter the maximum number of *: ");

            int n = Convert.ToInt32(Console.ReadLine());

 

            Console.WriteLine("\nPattern 1 - Left Aligned:\n");

                for (int i = 1; i <= n; i++)

                {

                      for (int j = 1; j <= i; j++)

                            Console.Write("*");

                      Console.WriteLine();

            }

 

                Console.WriteLine("\nPattern 2 - Right Aligned:\n");

                for (int i = n; i >= 1; i--)

                {

                      for(int j = 0; j < n - i; j++)

                            Console.Write(" ");
