Solution: Reverse Linked List
Explore how to reverse a singly linked list efficiently by manipulating pointers in place. Understand the step-by-step algorithm that updates node connections without extra memory, ensuring optimal time and space complexity. This lesson guides you through initializing pointers, reversing node links, and updating the head to achieve a reversed linked list in a single pass.
Statement
Given the head of a singly linked list, reverse the linked list and return its updated head.
Constraints:
Let n be the number of nodes in a linked list.
-
n
