BST and AVL tree methods-2

I am looking for a freelancer who is proficient in Java programming language to improve existing code for BST and AVL tree methods. The ideal candidate should have experience in working with data structures and algorithms.

Skills and experience required:

- Strong proficiency in Java programming language
- Knowledge of BST and AVL tree methods
- Experience in improving existing code
- Familiarity with data structures and algorithms

For the program, you are not allowed to add more libraries or add more classes. You are allowed to add more methods if needed. The codes you need to do are in the file

The project involves improving the existing code for BST and AVL tree methods, so the freelancer should be able to understand and analyze the code to make necessary enhancements.

After the project is completed, a basic overview of the code improvements and changes made will be required. This will allow me to understand the changes and modifications made to the code.

Please only apply if you have experience in Java programming and improving existing code for data structures.
