Python 3: Project-based Python, Algorithms, Data Structures - Introduction to Trees and Binary Search Trees

The video tutorial explains how to remove nodes from a binary tree, focusing on nodes with no children and nodes with one child. It covers the logic and conditions needed to handle these scenarios, including testing and debugging the code. The tutorial concludes by introducing the next topic: removing nodes with two children.

What is the first step to remove a node with one child in a binary tree?

Explain how to handle the case when trying to delete the root node.

What conditions must be checked when deleting a node with no children?

How do you modify the parent node when deleting a node with one child?

What is the significance of checking if the previous node exists when deleting the root?

Describe the logic used when the current node has a left child but no right child.

What happens when trying to delete a node that has both left and right children?
