Solution: Remove Nth Node from End of List
Explore the two pointers pattern to remove the nth node from the end of a singly linked list in a single traversal. Understand how moving one pointer ahead by n creates a gap that helps identify the node to remove. This lesson walks you through an optimized approach 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
. ...
