Questions & Step-by-Step Solutions
Which of the following is NOT a valid way to implement a binary tree in Python?
Step 1: Understand what a binary tree is. A binary tree is a data structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Know the common ways to implement a binary tree in Python. This usually involves using classes or lists to represent nodes and their relationships.
Step 3: Recognize that a set in Python is a collection type that does not maintain any order of elements and does not allow duplicate values.
Step 4: Realize that because a binary tree requires a specific structure (with ordered nodes and the possibility of duplicates), a set cannot be used to represent it.
Step 5: Conclude that the question is asking for the option that does NOT correctly implement a binary tree, and since a set cannot maintain the necessary structure, it is the correct answer.
