DIY: Reverse Nodes in k-Group
Explore how to reverse nodes in a linked list in groups of k using only constant extra space. This lesson helps you understand in-place node manipulation, a key skill for coding interviews involving linked list problems, by implementing a function that modifies the list structure while preserving node values.

Problem statement
Given a linked list, you will reverse the nodes of the linked list k at a time and return the modified list.
k is a positive integer and is less than or equal to the length of the linked list. If the number of nodes is not a multiple of k, then the nodes left in the end ...
