Solution: Remove Duplicates from a Linked List

Understand how to remove duplicate nodes from a singly linked list by traversing the list and updating pointers. This lesson helps you implement an efficient solution with O(n²) time complexity and constant space usage, preparing you for linked list problems in coding interviews.

We'll cover the following...

Statement

Given the head of a singly linked list, remove any duplicate nodes from the list in place, ensuring that only one occurrence of each value is retained in the modified list.

Constraints:

Let n be the number of nodes in a linked list.

  • 00 \leq n 500\leq 500

  • ...
