Solution: Reverse Nodes in Even Length Groups

Let's solve the Reverse Nodes in Even Length Groups problem using the In-Place Manipulation of a Linked List pattern.

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:
