Remove Duplicates
Understand how to remove duplicates from singly linked lists by using hash tables to track seen elements. Explore a Python method that iterates through the list, identifies duplicates, and modifies pointers to exclude them, helping you clean linked list data efficiently.

In this lesson, we will use a hash table to remove all duplicate entries from a single linked list. For instance, if our singly linked list looks like this:
1 - 6 - 1 - 4 - 2 - 2 - 4
Then the desired resulting singly linked list should take the form:
1 - 6 - 4 - 2
Below is another example to illustrate the concept of removing duplicates:
Algorithm #
The general approach to solve this problem is to loop through the linked list once and keep track of all the data held at ...
