Solution: Reverse Linked List II

Explore how to reverse a specified sublist in a singly linked list by manipulating pointers in place. Understand both a naive swapping approach and an optimized method using a dummy node to achieve O(n) time and O(1) space complexity. Gain skills to perform memory-efficient linked list reversals that maintain 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
  • 5000-5000 \leq node.value 5000\leq 5000
  • 11 \leq left \leq
