LeetCode – Reverse Nodes in k-Group (Java) Given a linked list, reverse the nodes of a linked list k at a time and return its modified 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 nodes, only nodes itself may be changed.

Given a linked list of size N.The task is to reverse every k nodes (where k is an input to the function) in the linked list.. Example 1: Input: LinkedList: 1->2->2->4->5->6->7->8 K = 4 Output: 4 2 2 1 8 7 6 5 Explanation: The first 4 elements 1,2,2,4 are reversed first and then the next 4 elements 5,6,7,8.

Each of the three groups is reversed in the output. Notes. The function has two parameters: head of the given linked list and k. Return the head of the linked list after reversing the groups of nodes in it.
