DIY: Reverse Nodes in k-Group
Explore how to reverse nodes in a linked list k nodes at a time without altering node values using JavaScript. Understand how to implement the reverseLinkedList function that modifies the node order efficiently with O(1) extra memory, while preserving nodes that do not form a complete group. This lesson helps you master linked list manipulation, useful for coding interviews and real-world applications.

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 ...
