Solution: Rotate List
Let’s solve the Rotate List problem using the In-Place Manipulation of a Linked List pattern.
We'll cover the following...
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, 500]....
