ByBinary Tree Traversal Techniques. Three recursive techniques for binary tree traversal In each technique, the left subtree is traversed recursively, the right subtree is traversed recursively, and the root is visited

ByBinary Search Tree. By : Budi Arifitama Pertemuan ke 12. Binary Search Trees. Objectives . Upon completion you will be able to: Create and implement binary search trees Understand the operation of the binary search tree ADT Understand the algorithm of BST ( Insert,remove )

ByPriority Queues and Heaps. CMPT 225. Remember Queues?. A queue should implement at least the first two of these operations: insert – insert item at the back of the queue remove – remove an item from the front peek – return the item at the front of the queue without removing it

ByLecture - 11 on Data Structures. Threaded Trees. Binary trees have a lot of wasted space: the leaf nodes each have 2 null pointers We can use these pointers to help us in inorder traversals We have the pointers reference the next node in an inorder traversal; called threads
