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 when removing a node with one child in a binary tree?

• Check if the node has two children

• Check if the node has no children

• Check if the node is the root

• Check if the node has a left child

When deleting a node with a right child only, what should the parent node point to?

• The left child of the node

• The right child of the node

• The root of the tree

• The previous node

In the case of a node with a left child only, what adjustment is made in the deletion process?

• The parent node points to the right child

• The root is set to the right child

• The parent node or root points to the left child

• The node is left unchanged

What scenario is introduced at the end of the video for future discussion?

• Deleting the root node

• Deleting a node with both left and right children

• Deleting a node with one child

• Deleting a node with no children
