IDG. Figure 1. Traversing a doubly-linked list forward and backward. CRUD operations in doubly-linked lists. Creating, inserting, and deleting nodes are all common operations in a doubly-linked list.

IDG. Figure 2. The initial singly linked list consists of a single Node (A) This operation has a time complexity of O(1)–constant. Recall that O(1) is pronounced “Big Oh of 1.” (See Part 1 ...

Examines several design issues, including selection of data structures based on operations to be optimized, algorithm encapsulation using classes and templates, and how and when to use recursion.

One such ADT is a doubly linked list structure. In this article, I present a conventional implementation and an alternative implementation of the doubly linked list ADT, with insertion, traversal and ...
