Understanding the Reverse Nodes in k- Group Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given the head of a linked list, reverse the nodes of the 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 left-out nodes, in the end, should remain as it is. You may not alter the values in the list's nodes, only nodes themselves may be changed.
