DIY: Reverse Nodes in k-Group
Explore how to reverse nodes in groups of k within a linked list without changing node values and using constant extra space. Learn to implement an efficient linked list manipulation algorithm, a frequent coding interview topic, and understand how to handle edge cases when the list length isn't a multiple of k.

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 ...
