61. Rotate List

Practice Rotate List for free on NudgeCode: Medium, Linked List pattern. Write it in Python or JavaScript, run the tests in your browser, and ask for a hint when you are stuck.

Rotate a linked list to the right by k places: each step moves the last node to the front. Return the head of the rotated list. k can be larger than the length of the list, and an empty list stays empty.

Example

head = [1,2,3,4,5], k = 2  ->  [4,5,1,2,3]
head = [0,1,2], k = 4      ->  [2,0,1]
