Problem: Remove Linked List Elements

Easy
15 min
Explore how to remove all nodes containing a specified value from a linked list by performing in-place manipulation. This lesson helps you understand how to optimize linked list operations for both memory and speed while practicing hands-on coding techniques.

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].

  • 11 \leq Node.value 50\leq 50

  • 00 \leq k 50\leq 50
