Which of the following is 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: Decide how you want to represent the binary tree in Python. You can use different data structures like lists, dictionaries, or custom classes.
Step 3: If using a custom class, define a class for the tree nodes. Each node should have properties for the value it holds and pointers to its left and right children.
Step 4: Create a binary tree by instantiating nodes and linking them together according to the binary tree rules.
Step 5: If using lists, you can represent the tree using indices, where the left child of a node at index i is at index 2*i + 1 and the right child is at index 2*i + 2.
Step 6: If using dictionaries, you can use keys to represent node values and values to represent the left and right children.
