Solution: Return the Nth Node from End

Explore how to find the nth node from the end of a linked list using two main approaches. Understand the double iteration method by calculating list length and the two-pointer technique that efficiently locates the node in a single pass. This lesson helps you implement both strategies in Python and analyze their time and space complexity to prepare for coding interviews.

Statement

Given the head of a linked list, return the nthn^{th} node from the end of the linked list.

Constraints:

  • The number of nodes in the list is kk.

  • 11 \leq kk ...
