Algorithms Linked List with no NULLs A Linked list is a dynamic data structure which can grow or shrink on demand. It is usually implemented using NULLs, we will consider an alternative no NULL approach and use placeholder nodes.
Algorithms Designing a Binary Search Tree with no NULLs A Binary Search Tree (BST) is usually implemented using NULLs in C or C++. This article explores an alternative approach of using placeholder nodes. Here the Binary Search Tree will be implemented in C++.
