Solution: Reverse Linked List II

Explore how to reverse a segment of a singly linked list in place by directly adjusting node pointers. This lesson guides you through initializing dummy nodes and using pointers to efficiently reverse a sublist from left to right. You will learn to implement this with O(n) time complexity and constant space, improving over naive approaches while preserving the list integrity.

Statement

Given a singly linked list with nn nodes and two positions, left and right, the objective is to reverse the nodes of the list from left to right. Return the modified list.

Constraints:

  • 11 \leq n 500\leq 500
