Rotate List Given a list, rotate the list to the right by k places, where k is non-negative. Example Input :-head = [5, 4, 10, 15, 1], k = 2 Output :-[15, 1, 5, 4, 10] Input :-head = [0, 1, 2], k = 4 Output :-[2, 0, 1] Solution. Interesting. An easier way to understand the problem is to rotate the tail of the linked list by k places to to the head in counter-clock wise. Reverse Linked List II. This is the best place to expand your knowledge and get prepared for your next interview. The Problem:Given a list, rotate the list to the right by k places, where k is non-negative.For example:Given 1->2->3->4->5->NULL and k = 2,return 4->5->1->2->3->NULL.Notes:Two pointers with one k elements ahead, so when the faster reach null, the slower one is the new head.Attention that k could be bigger than the length, so within the iteration, if fast… You have given a singly linked list and an integer k, rotate the linked list to the right by k places.
