What are some examples of circular linked lists?

Can you explain what a circular linked list is?

A circular linked list is a data structure where the last node points back to the first node, forming a circle.

What are some practical examples of circular linked lists?

Circular linked lists are used in applications like round-robin scheduling, multiplayer games, and buffering.

How does a circular linked list differ from a regular linked list?

In a regular linked list, the last node points to null, while in a circular linked list, it points back to the first node.

Can you give me a code example of a circular linked list?

Sure! Here's a simple implementation in Python:

class Node: def init(self, data): self.data = data self.next = None

class CircularLinkedList: def init(self): self.head = None

def append(self, data):
    new_node = Node(data)
    if not self.head:
        self.head = new_node
        new_node.next = self.head
    else:
        current = self.head
        while current.next != self.head:
            current = current.next
        current.next = new_node
        new_node.next = self.head

This code creates a circular linked list and allows you to append new nodes.
