Pull Request Overview
This PR introduces two new linked list manipulation algorithms: rotating a linked list to the right by k places and reordering a linked list by odd and even indices.
- Implements
rotateRightfunction that rotates a linked list to the right by k positions using a circular linked list approach - Implements
oddEvenLinkedListfunction that groups nodes at odd indices together followed by nodes at even indices - Both implementations include helper functions for printing lists and self-test code for browser environments
