Solution: Rotate List
Explore how to rotate a singly linked list to the right by k positions in a performant way. Understand how to compute the list length, create a circular list, and then break it at the right point to achieve rotation with only one full traversal. This lesson helps you implement and analyze this core linked list manipulation pattern efficiently.

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,...
