ByBinary Trees. Chapter 6. Linked Lists Suck. By now you realize that the title to this slide is true… When we are talking about searching or representing data structures that need a hierarchical structures. We need a better structure… So we get binary trees. Tree definition.

ByGoals of this Course. Reinforce the concept that costs and benefits exist for every data structure. Learn the commonly used data structures. These form a programmer's basic data structure ``toolkit.'‘ Understand how to measure the cost of a data structure or program.

ByAVL Trees. AVL Trees. An AVL tree is a binary search tree with a balance condition. AVL is named for its inventors: A del’son- V el’skii and L andis AVL tree approximates the ideal tree (completely balanced tree). AVL Tree maintains a height close to the minimum. Definition:

ByChapter 7. 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 Write application programs using the binary search tree ADT Design and implement a list using a BST
