Problem: Remove Nth Node From End of List

Explore how to remove the nth node from the end of a singly linked list by applying the two-pointer method. Learn to create a dummy node and use fast and slow pointers to perform a single-pass removal, efficiently handling edge cases and understanding time and space complexity.

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

  • ...
