Solution: Reverse Linked List II

Explore how to reverse a sublist in a singly linked list from a given left to right position using in-place pointer manipulation. Understand the use of dummy nodes and iterative pointer adjustments to achieve an O(n) time and O(1) space solution. This lesson helps you practice efficient linked list restructuring without extra space.

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
  • 5000-5000 \leq node.val 5000\leq 5000
  • 11 \leq left \leq
