CSCI 261 - Programming Concepts - Spring 2022

This lab is due by Thursday, May 05, 2022, 11:59 PM.
As with all labs you may, and are encouraged, to pair program a solution to this lab. If you choose to pair program a solution, be sure that you individually understand how to generate the correct solution.

The BinarySearchTree Class

We are going to now make a new templated class called BinarySearchTree. This will necessitate creating a new struct for a TreeNode to store the parent, left, and right pointers.

The BinarySearchTree class needs to have the following public methods created:

• BinarySearchTree() - Constructor that sets the root pointer to be null and set the size to be zero
• BinarySearchTree(const BinarySearchTree& OTHER) - Copy Constructor that performs a deep copy of the other tree
• ~BinarySearchTree() - Destructor that deallocates the entire tree, sets the root pointer to be null, sets the size to be zero
• BinarySearchTree& operator=(const BinarySearchTree& OTHER) - Copy Assignment Operator that deallocates the existent tree (if any) then performs a deep copy of the other tree
• void insert(const T VAL) - inserts a node for the given VAL. If VAL is less than the root, recursively attempt to add to the left subtree. If VAL is greater or equal to the root, recursively attempt to add to the right subtree. Increments the size by one.
• int size() const - returns the current total number of nodes in the tree

To test your implementation, perform in main.cpp the following steps in order:

1. Create a BinarySearchTree of integers
2. Add the value 6
3. Add the value 5
4. Add the value 7
5. Add the value 1
6. Add the value 2
7. Add the value 9
8. Add the value 3

You'll verify your insert() is working correctly in the corresponding assignment.

Lab Submission

Submit your BinarySearchTree.hpp, TreeNode.hpp, main.cpp, Makefile file(s).

You will submit your solution to this lab with the rest of SetXC. Detailed instructions for doing this are posted in Assignment XC.
