FAQs

Question: What is the difference between a tree and a graph?
Answer: A tree is a special type of graph that is acyclic and connected, while a graph can have cycles and may not be connected.

Question: How do I implement a binary search tree in Python?
Answer: You can implement a binary search tree by creating a class for the nodes and defining methods for insertion, deletion, and traversal.
