Solution: Remove Nth Node from End of List
Understand how to efficiently remove the nth node from the end of a singly linked list using the two-pointer method. This lesson guides you through the steps to implement this solution with a single pass, reducing time complexity. You will learn to move one pointer ahead by n steps, then move both pointers together to identify and remove the target node, all while maintaining constant 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
. ...
