Bidirectional Traversal
Bidirectional traversal refers to the ability to navigate through a data structure in both forward and backward directions. This capability is most commonly associated with doubly linked lists, where each node contains two references: one pointing to the next node and another pointing to the previous node. This dual-linking enables users to move through the list from the beginning to the end or from the end to the beginning with equal ease. Bidirectional traversal is advantageous in scenarios where it's necessary to access elements in reverse order or when frequent insertion and deletion operations are performed at both ends of the list. It enhances flexibility and efficiency in data manipulation tasks, making doubly linked lists and other bidirectionally traversable structures valuable in various computer science and software development applications.
