Solution: Reverse Nodes in Even Length Groups

Explore how to reverse nodes within even-length groups in a linked list using an in-place algorithm. Understand how to manage pointers to reverse segments efficiently without extra space. This lesson equips you to manipulate linked lists by processing groups based on length and integrating reversed sections seamlessly.

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: ...
