Reverse Nodes in Even Length Groups
Understand how to reverse nodes grouped by ascending natural numbers in a linked list where only even-length groups are reversed. Learn to manipulate linked lists in-place with O(n) time and O(1) space complexity. This lesson helps you implement the solution with clear problem analysis and hands-on coding practice.

Statement
Given the head of a linked list, the nodes in it are assigned to each group in a sequential manner. The length of these groups follows the sequence of natural numbers. Natural numbers are positive whole numbers denoted by
