How do I traverse a circular linked list?

How do I traverse a circular linked list?

To traverse a circular linked list, start at any node and follow the next pointers until you return to the starting node.

Can you provide a code example for that?

Sure! Here's a simple example in Python:

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

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

    def traverse(self):
        if not self.head:
            return
        current = self.head
        while True:
            print(current.data)
            current = current.next
            if current == self.head:
                break

What if the list is empty?

If the list is empty, the traverse method will simply return without printing anything.
