Solution: Reverse Linked List II

Explore how to reverse a portion of a singly linked list by adjusting pointers efficiently in-place. This lesson teaches you to implement an optimized O(n) time and O(1) space solution by using a dummy node and pointer manipulation, enabling you to confidently solve linked list reversal problems in coding interviews.

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
