Problem: Remove Nth Node From End of List

Understand how to remove the nth node from the end of a singly linked list with a single traversal. Learn to apply the two-pointer technique and handle edge cases by introducing a dummy node. This lesson helps you implement an efficient, constant space algorithm using fast and slow pointers to modify linked lists.

We'll cover the following...

Statement

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

Constraints:

  • The number of nodes in the list is sz

  • 1≤1 \leq sz ≤30 ...
