DIY: Reverse Nodes in k-Group
Explore how to reverse nodes of a linked list in groups of k, preserving node values and using only constant additional memory. Understand the problem constraints and implement a function to modify linked lists in-place, preparing you for algorithmic coding interview questions involving linked list manipulation.

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 ...
