Solution Review: Remove Duplicates From a Linked List

Explore how to identify and remove duplicate values from a linked list by iterating through nodes in C#. Understand the implementation details and analyze the O(n²) time complexity of this straightforward approach, preparing you to handle linked list challenges effectively.

We'll cover the following...

Solution

...
C#
using System;
namespace chapter_3
{
    class Challenge_8
    {
        static void Main(string[] args)
        {
            LinkedList list = new LinkedList();
            for (int i = 1; i < 4; i++)
            {
                list.InsertAtHead(i);    // inserting value in the list
                list.PrintList();
            }
            list.InsertAtHead(2);
            list.PrintList();  //after adding more elements
            list.InsertAtHead(4);
            list.PrintList();  //after adding more elements
            list.InsertAtHead(1);
            list.PrintList();  //after adding more elements
            string removeDuplicate = list.RemoveDuplicates(); // calling removeDuplicates function
            Console.WriteLine("List after deleting duplicates from list :" + removeDuplicate);
            return;
        }
    }
}

In this implementation, ...
