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 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:
-
