Problem: Remove nth Node from End of List

Medium
30 min
Explore how to effectively remove the nth node from the end of a singly linked list using the two pointers technique. This lesson helps you understand the problem constraints and guides you through developing a solution by assessing the linked list structure. You will practice by implementing your code in a hands-on environment and receive hints to navigate challenges efficiently.

Statement

Given the head of a singly linked list and an integer n, remove the nth node from the end of the list and return the head of the modified list.

Constraints:

  • The number of nodes in the list is kk.

  • 11 \leq kk 103\leq 10^3

  • 103−10^3 \leq Node.value 103\leq 10^3

  • 11 \leq n k\leq k
