Solution: Reverse Linked List
Explore how to reverse a singly linked list using in-place manipulation by adjusting node pointers. Understand initializing pointers, iterating through the list, and updating the head to complete reversal. Gain insight into an optimized solution with linear time complexity and constant space usage.
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.
