Solution: Rotate List
Understand how to rotate a singly linked list to the right by k positions efficiently. Explore a method that uses a single traversal to form a circular list and then breaks it at the right point to produce the rotated list with constant extra space.

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,...
