Almost every enterprise application uses various types of data structures in one or the other way. For example, we can store a list of items having the same data type using the array data structure. In this traversal technique the traversal order is rootleftright i. For example, the insert function below may want to change the root pointer. A binary tree is a structure comprising nodes, where each node has the following 3 components.

Using trie, search complexities can be brought to optimal limit key length. A binary search tree or bst as it is popularly called is a binary tree that fulfills the following conditions. The tree data structure can form some of the most useful and complex data structures in all of programming. Binary tree structure a quick introduction to binary trees and the code that operates on them section 2.

For example, if x is the parent node of y, then the value of x follows a specific order with respect to the value of y and the same order will be followed across the tree. A tree whose elements have at most 2 children is called a binary tree. The binary search tree is some times called as bst in short form.
