Python 3: Project-based Python, Algorithms, Data Structures - Project: Complete quote finder using hash table

The video tutorial covers the implementation of a binary search tree (BST) in Python, focusing on the insert method. It begins with an introduction to the node and BST classes, explaining the use of underscore methods as private. The tutorial then demonstrates inserting the root node and subsequent left and right children, highlighting the importance of recursion for handling various insertion scenarios. The video concludes with testing the insert method to ensure it functions correctly, setting the stage for future videos on inorder traversal.

What is the initial value of the left and right children in the node class?

• Empty String

• Zero

• None

• True

What is the purpose of methods with an underscore prefix in Python?

• To indicate private methods

• To indicate deprecated methods

• To indicate public methods

• To indicate static methods

What is the first step in the insert method for a binary search tree?

• Check if the root is None

• Insert the node at the end

• Insert the node at the beginning

• Check if the tree is full

How does the insert method determine where to place a new node?

• By comparing the node's data with the root

• By inserting at the rightmost position

• By checking the height of the tree

• By inserting at the leftmost position

What happens if the left child of a node is not None during insertion?

• The node is discarded

• The node is inserted as the right child

• The node is inserted as the left child

• The method is called recursively

In the insert method, what is the condition to insert a node as the right child?

• If the node's data is not a number

• If the node's data is equal to the current node's data

• If the node's data is greater than the current node's data

• If the node's data is less than the current node's data

What is the purpose of using recursion in the insert method?

• To find the correct position for the new node

• To handle multiple insertions at once

• To simplify the code

• To increase the speed of insertion

What is the expected output after inserting nodes F, C, and G?

• F, G, C

• C, F, G

• F, C, G

• G, F, C

Why was the order of insertion for nodes E and H switched in the video?

• To simplify the code

• To cover all modes of insertion

• To avoid errors

• To test a new method

What is the next topic to be covered after the insert method?

• Preorder traversal

• Level order traversal

• Postorder traversal

• Inorder traversal
