Problem: Remove Nth Node From End of List

Explore how to remove the nth node from the end of a singly linked list using the two pointer method. Understand the use of a dummy node and the step-by-step approach to traverse and modify the list in one pass, while achieving linear time complexity and constant space usage.

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\leq 30

  • ...
