Solution: Reverse Linked List
Explore the process of reversing a singly linked list by manipulating pointers in place. This lesson helps you understand using three pointers to reverse node links efficiently, achieving linear time complexity and constant space usage. You'll learn the step-by-step approach to implement and optimize this fundamental linked list operation.
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.
