Solution: Remove Linked List Elements

Understand how to remove nodes from a linked list where the node's value matches a target integer. Explore the in-place manipulation technique using a dummy node and two pointers to traverse and modify the list efficiently without extra space. Learn to implement this solution with O(n) time complexity and constant space complexity.

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 ...
