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 give me a code example in Python?

Sure! Here's a simple example:

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

# Function to traverse circular linked list

def traverse_circular_linked_list(head):
    if head is None:
        return
    current = head
    while True:
        print(current.data)
        current = current.next
        if current == head:
            break

What are the advantages of using a circular linked list?

Circular linked lists allow for efficient memory usage and can simplify certain operations like merging lists or implementing queues.

Are there any drawbacks to using them?

Yes, one drawback is that they can be more complex to implement and manage, especially when it comes to avoiding infinite loops.
