Different types of linked lists

There are many ways to implement a linked list, but its classification depends on its structural characteristics.

Linked lists have three broad categories:

• Singly Linked List (one-way traversal)
• Doubly Linked List (two-way traversal)
• Circular Linked List (last node links back to the first)

Most linked lists share fundamental operations, but their structure affects efficiency and capabilities. For example, doubly linked lists enable O(1) backward traversal, unlike singly linked lists.
