Question
Chapter 21, Problem 22RQE
Program Plan Intro
Binary tree:
- It is a tree data structure which comes under hierarchical data structure.
- It is made of nodes that have a left child, right child and a data element.
Nodes in a binary tree:
- The node which is at the top of a binary tree is called “root node”.
- The element that has children is known as “parent node”.
- The element that is under an element is known as “children”.
- The element or the node that has two children is called “leaves” or “external nodes”.
- In binary tree, each node should have at most two children.

What is the time complexity of your function? def find_median(self):arrow_forwardBinary Search Tree Using a binary search tree, you are tasked with building a dictionary program which you can store a word with its definition. Each node of the tree will contain the word and definition. The word is what will be used as the key to sort our data. The dictionary should allow you to search for a word. If the word exist then the definition will display. You can also add words to the dictionary. For testing you should be able to display the current word list. The dictionary will populate from a data file and new words will be saved to the file as well.
