Solution: Rotate List
Explore how to rotate a singly linked list to the right by k positions efficiently in this lesson. Understand the step-by-step algorithm that involves creating a circular list, adjusting pointers, and breaking the cycle to achieve rotation. This approach avoids repeated shifts and operates in linear time with constant space. By the end, you will be able to implement this solution confidently for linked list manipulation tasks.
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,...
