Problem: Remove Linked List Elements

easy
15 min
Understand how to remove nodes from a linked list where node values equal a given integer by applying in-place manipulation techniques. This lesson helps you implement efficient and memory-optimized solutions for linked list problems.

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 linked list is in the range [0,103][0, 10^3].

  • 1≤1 \leq Node.value ≤50\leq 50

  • 0≤0 \leq k ≤50\leq 50
