Which of the following is NOT a valid way to implement a binary tree in C++?
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: Learn about different ways to implement a binary tree. Common methods include using arrays, vectors, and linked lists.
Step 3: Recognize that arrays and vectors can be used to represent binary trees by storing elements in a specific order, where the parent-child relationship can be calculated using indices.
Step 4: Understand that a linked list is typically used for linear data structures, not for trees. In a binary tree, each node should point to its children, which is not how a standard linked list operates.
Step 5: Conclude that while arrays and vectors are valid implementations for binary trees, using a linked list is not standard and therefore is NOT a valid way to implement a binary tree.
