Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code these pattern.

Practical Implementation:

using System;

namespace patternProblem
{
    class Pattern17
    {
        public static void Main()
        {
            Console.WriteLine("Enter iteration times: ");
            int n = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine("-----Output-----");
            Console.WriteLine();
            for (int i = n; i >= 1; i--)
            {
                for (int j = 1; j <= i; j++)
                {
                    Console.Write(j + " ");

                    if (j == i)
                    {
                        for (int k = (j - 1); k >= 1; k--)
                        {
                            Console.Write(k + " ");
                        }
                    }
                }
                Console.WriteLine();
            }

            Console.ReadKey();
        }
    }
}

Output:
The input number here is 5. So, the program will iterate five times. The output is shown below:

Enter iteration times:
5
-----Output-----

1 2 3 4 5 4 3 2 1
1 2 3 4 3 2 1
1 2 3 2 1
1 2 1
