Data Structures and Algorithms The Complete Masterclass - Binary Tree

The video tutorial introduces binary trees, explaining their structure where each node has a maximum of two children. It covers the implementation of binary trees, comparing them to linked lists, and details the node structure. The tutorial also discusses various types of binary trees, including full, complete, perfect, balanced, and degenerate binary trees, highlighting their unique characteristics and differences.

What is the maximum number of children a node can have in a binary tree?

• One

• Two

• Four

• Three

In a binary tree implementation, what is used to represent a missing child?

• Null

• Negative One

• Zero

• Empty String

Which of the following is NOT a type of binary tree?

• Full

• Complete

• Degenerate

• Partial

In a full binary tree, how many children can a node have?

• Zero or One

• Any number

• One or Two

• Zero or Two

What is a key characteristic of a complete binary tree?

• All nodes are right-aligned

• Nodes are left-aligned at the last level

• All nodes have two children

• All levels are fully filled

In a perfect binary tree, what is true about the leaf nodes?

• They are at different depths

• They are at the same depth

• They have no children

• They have one child

What is the main factor considered in a balanced binary tree?

• Height of subtrees

• Number of nodes

• Depth of root

• Number of leaves

In a degenerate binary tree, how many children does each parent node have?

• Two

• Zero

• Three

• One

Which type of binary tree resembles a linked list?

• Full

• Complete

• Degenerate

• Perfect

What should you do to avoid confusion with different types of binary trees?

• Ignore definitions

• Avoid learning

• Refer to resources

• Memorize examples
