Solution Review: Calculating the Size of a Tree
Explore how to calculate the total number of nodes in a binary tree using both iterative and recursive methods. This lesson helps you understand and implement these techniques in Python to solve tree size problems effectively.

In this lesson, we will review a solution to the problem of determining the size of a binary tree.
The “size” of a binary tree is the total number of nodes present in the binary tree. We will explicitly define this quantity in greater detail and cover a strategy for how one may calculate this quantity in the binary tree data structure we have been building in this chapter.
We will discuss an iterative and a recursive approach for solving this challenge.
Iterative Approach
In the iterative solution, we’ll make use of a stack ...
