Solution: Rotate List
Understand how to rotate a singly linked list to the right by a given number of positions efficiently. This lesson teaches how to calculate the list length, create a circular list to simplify rotation, and then break the cycle to form the rotated list. You will learn to implement this in a single pass with constant space, mastering in-place linked list manipulations.

Statement
You are given the head of a singly linked list and a non-negative integer k. Your task is to rotate the list to the right by k positions.
A right rotation by 1 means the last node becomes the new head, and every other node shifts one position to the right.
Return the head of the rotated linked list.
Constraints:
The number of nodes in the list is in the range
[0,...
