Lecture notes 15 trees css 501 – data structures and object oriented programming – professor clark f. olson reading: carrano, chapter 10.1 10.2 introduction to trees the data structures we have seen so far to implement abstract data types (arrays, linked lists) maintain the objects in some order.

Importance for tree data structure: 1. one reason to use trees might be because you want to store information that naturally forms a hierarchy. for example, the file system on a computer: 2. trees (with some ordering e.g., bst) provide moderate access search (quicker than linked list and slower than arrays). 3. In above tree, a is a root node 2. edge in a tree data structure, the connecting link between any two nodes is called as edge. in a tree with 'n' number of nodes there will be a maximum of 'n 1' number of edges. 3. parent in a tree data structure, the node which is predecessor of any node is called as parent node. in. The time complexity of search insert delete is o (log n) . a 2 3 tree is a b tree of order 3. properties of 2 3 tree: nodes with two children are called 2 nodes. the 2 nodes have one data value and two children. nodes with three children are called 3 nodes. the 3 nodes have two data values and three children. data is stored in sorted order.

An avl tree is a balanced binary search tree where every node in the tree satisfies the following invariant: the height difference between its left and right children is at most 1. hence, all sub trees of an avl tree are themselves avl. the height difference between children is referred to as the balance factor of the node. A 2 3 4 tree is like a 2 3 tree, but it allows 4 nodes, which are nodes that have four children and three data items. 2 3 4 trees are also known as 2 4 trees in other books. although a 2 3 4 tree has more efficient insertion and deletion operations than a 2 3 tree, a 2 3 4 tree has greater storage requirements. 3.
