Solution: Remove Linked List Elements

Explore how to efficiently remove all nodes containing a given value from a linked list by manipulating pointers in-place. Understand the use of dummy nodes and two-pointer traversal to update the list without extra space, ensuring your algorithm runs in linear time and constant space.

Statement

You are given the head of a linked list and an integer k. Remove all nodes from the linked list where the node’s value equals k, and return the head of the updated list.

Constraints:

  • The number of nodes in the list is in the range ...
