Solution: Remove Duplicates from Sorted List

Understand how to remove duplicates from a sorted linked list by traversing and altering pointers in-place. This lesson helps you implement a one-pass solution that efficiently skips duplicate nodes, ensuring each element appears only once. You will learn the logic behind pointer manipulation for memory optimization and grasp the time and space complexity of this approach.

Statement

Given the head of a sorted linked list, remove all duplicates such that each element appears only once, and return the list in sorted order.

Constraints:

  • 00 \leq n 300\leq 300, where n is the number of nodes in the list. ...
