How do I traverse a linked list in programming?

How do I traverse a linked list in programming?

To traverse a linked list, you start at the head node and follow the next pointers until you reach the end.

Can you show me a code example in Python?

Sure! Here's a simple example:

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

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

    def traverse(self):
        current = self.head
        while current:
            print(current.data)
            current = current.next

What if the linked list is empty?

If the linked list is empty, the head will be None, and the traversal function will not enter the loop.

Are there different types of linked lists?

Yes, there are several types, including singly linked lists, doubly linked lists, and circular linked lists.
