What is a circular linked list?

What is a circular linked list?

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

What are the advantages of using a circular linked list?

Circular linked lists allow for efficient traversal and can be useful in applications like round-robin scheduling.

Can you show me an example of how to implement one in Python?

Sure! Here's a simple implementation of a circular linked list 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

# Example usage:
cll = CircularLinkedList()
cll.append(1)
cll.append(2)
cll.append(3)

What are some common use cases for circular linked lists?

Common use cases include implementing circular queues, managing resources in operating systems, and in multiplayer games for player turns.
