Java Binary Trees Why isn't it working? --- //adds a new Node to the tree (in a way of a Binary Search tree): public void add(int data){ insert(this.root, data); } private void insert(Node node, int data){ if (node == null){ //stops the recursion, some node will have ...

binary search trees, ones that ensure that, regardless of the order of the data inserted, the tree maintains a log2nrunning time. In this article, we'll briefly discuss two self-balancing binary search trees: AVL trees and red-black trees. Following that, we'll take an in-depth look ...
