Exploring the Circular Singly Linked List in Python
If you’re new to data structures, the concept of a circular singly linked list might sound like a mouthful. But don’t worry! In this guide, we’ll break down everything you need to know about this fascinating structure, using simple language and clear examples. By the end, you’ll understand how to implement and manipulate these lists in Python.
What is a Circular Singly Linked List?
A circular singly linked list is a variation of the linked list in which the last item points back to the first item. This creates a circular structure that allows us to loop through the list indefinitely, which can be very handy in applications where the end of the list naturally connects back to the beginning (like in a round-robin scheduler).
Each element in the list is called a node, and it contains:
- Value: The data stored in the node.
- Next: A reference (or pointer) to the next node in the list.
