PROBLEM OF THE DAY : 10/08/2024 | Rotate a Linked List

Welcome to the daily solving of our PROBLEM OF THE DAY with Yash Dwivedi We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Linked List but also build up problem-solving skills.

Given the head of a singly linked list, the task is to rotate the linked list clockwise by k nodes, i.e., left-shift the linked list by k nodes, where k is a given positive integer smaller than or equal to length of the linked list.

Examples:

Input: linkedlist: 2->4->7->8->9 , k = 3 Output: 8->9->2->4->7 Explanation:@Rotate 1: 4 -> 7 -> 8 -> 9 -> 2 Rotate 2: 7 -> 8 -> 9 -> 2 -> 4 Rotate 3: 8 -> 9 -> 2 -> 4 -> 7
2->4->7->8->9
k=3
8->9->2->4->7
