Solution: Reverse Nodes in Even Length Groups

Explore how to reverse nodes in even-length groups of a linked list using an in-place approach. Understand managing pointers to alter node connections directly without extra space, while preserving odd-length groups, improving your grasp of linked list manipulation in coding interviews.

We'll cover the following...

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 (1,2,3,4...)(1,2,3,4...).

In other words: ...
