## Ch 13: Advanced Table Implementations

Ch 13: Advanced Table Implementations As we saw in chapter 11 the ordered binary tree ADT offers a good compromise between the rigid size and need for shifting in an array implementation and the need for sequential search found in an ordered or unordered linked list

## Balanced search trees: 2-3 trees.

Balanced search trees: 2-3 trees. 2-3 trees allow us to process ordered lists in more efficient way than binary trees with an ordering property. Recall that the worst case search efficiency in the later is O(N). All balanced trees guaranty at least O(logN) efficiency for

## Binary Search Tree (BST)

Binary Search Tree (BST). Properties: Each node has a value The left subtree contains only values less than the parent node’s value The right subtree contains only values greater than or equal to the parent node’s value. BST Example. BST Search Algorithm. if the root is NULL then

## Binary Trees

Binary Trees . Chapter 6. 6.1 Trees, Binary Trees, and Binary Search Trees . Linked lists usually are more flexible than arrays, but it is difficult to use them to organize a hierarchical representation of objects.

## Trees

Trees. Binary Trees. Tree Terminology. Trees are used to represent the relationship between data items. All trees are hierarchical in nature which means there is a parent-child relationship between "nodes" in a tree. The lines between nodes are called directed edges.

Binary Trees & Insertion. COP 3502. Binary Search Tree Insertion. Inserting a Node into a Binary Search Tree Similar to searching for a node We have to “trace out” the same path, to find where this node belongs in the tree. Let’s say we were going to search for 5 in the following tree:. 6.
