lab 15 Binary Trees part 2 Solved
Instructions: This lab continues our construction of Binary Trees. For this lab extend your previous implementation of Binary Search Tree with contains, delete, remove, existsInRange, and countInRange.

Write some test cases:
Create some test cases, using cxxtestgen, that you believe would cover all aspects of your code.
Memory Management:
Now that are using new, we must ensure that there is a corresponding delete to free the memory.
Ensure there are no memory leaks in your code! Please run Valgrind on your tests to ensure no memory leaks!
How to turn in:
Turn in via GitHub. Ensure the file(s) are in your directory and then:
• $ git add <files
• $ git commit
• $ git push
