Write a Program to sort the elements of the circular linked list.

Solution:

using System;

namespace LinkedListOpearation
{
    class Program
    {
        public static void Main()
        {
            var linkedList = new LinkedList();
            linkedList.Add(6);
            linkedList.Add(1);
            linkedList.Add(5);
            linkedList.Add(1);
            linkedList.Add(3);
            linkedList.Add(9);
            Console.WriteLine($"Circular Linked List");
            linkedList.Print();
            linkedList.Sort();
            Console.WriteLine($"After Sorting Circular Linked List");
            linkedList.Print();
            Console.ReadLine();
        }
    }
