Let's solve the Remove Nth Node from End of List problem using the Two Pointers pattern.

We'll cover the following

Statement

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

Constraints:

  • The number of nodes in the list is k.
  • 1≤1 \leq k ≤103\leq 10^3
  • −103≤-10^3 \le Node.value ≤103\le 10^3
  • 1≤1 \le n ≤\le k
