Solution: Remove Nth Node from End of List

Explore how to remove the nth node from the end of a singly linked list using the two-pointer approach. Understand the step-by-step algorithm, including pointer initialization, advancing the right pointer by n steps, and removing the target node. This method offers an efficient one-pass solution with O(N) time and O(1) space complexity.

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 ...
