Solution Review: Return the Nth Node From The End

Learn how to return the nth node from the end of a singly linked list using two approaches: a double iteration method that calculates list length and a more efficient two-pointer technique that finds the node in a single pass. Understand their time complexities and implementation details to solve linked list challenges effectively.

We'll cover the following...

- Solution 1: Double iteration
- - Time complexity
- Solution 2: Two pointers
- - Time complexity

using System;

{
    class Challenge_10
    {
        static void Main(string[] args)
        {
            LinkedList list = new LinkedList();    //creating list
            for (int j = 0; j <= 7; j++)
            {
                list.InsertAtHead(j);      //insertng data in list
                list.PrintList();
            }
            int num = 5;
            int nth = list.FindNth(num); // calling findNth function of the list
            Console.WriteLine(num + "th element from end of the list : " + nth);
            return;
        }
    }
}
