This challenge is about implementing a binary search tree with an insert method in Python.
A binary search tree is a data structure that allows fast search, insert, and delete operations. It is a tree where each node has at most two children, and the left child is less than the parent, and the right child is greater than the parent. The insert method adds a new node to the tree in the appropriate position based on its value.
Your task is to implement a binary search tree with an insert method in Python. The insert method should take a value and add a new node to the tree in the appropriate position based on its value. If the root input is None, return a tree with the only element being the new root node.
To complete this challenge, you need to meet the following requirements:
Insert will be tested through the following traversal:
You do not have to code the in-order traversal, it is part of the unit test.
In this challenge, you learned how to implement a binary search tree with an insert method in Python. You also learned the requirements and constraints of the challenge and saw an example usage of the insert method.
