Problem: Remove Nth Node From End of List

Explore how to remove the nth node from the end of a singly linked list using a two-pointer approach with a dummy node. Learn to implement this single pass, constant space algorithm in Java, improving your skills in linked list manipulation and pointer techniques.

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 ...
