Solution: Reverse Linked List II

Explore how to reverse a portion of a singly linked list in place by adjusting node pointers without extra memory. Understand and implement an optimized algorithm that improves time complexity to linear, ensuring efficient modification between given positions while maintaining the integrity of the overall list.

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
