PP 20.5 (page 801) Complete all missing methods in LinkedBinarySearchTree. Show test cases for all implemented methods, being sure to include edge cases for methods where applicable. Then, implement a balanced tree method for this class using the brute force method described in Section 20.5 of your textbook. Show test cases for two different degenerate trees, outputting the height of the tree before and after balancing the tree. Then, demonstrate insertions into a balanced tree that result in degenerate trees and rebalance the tree again. Hint: Copy the elements into an ArrayList using an in-order traversal. Recursively build a balanced tree using binary partitioning.
