Inserting node 45 makes the AVL tree unbalanced. A double rotation is required to rebalance the tree. What are the two rotations?
Added by Jeffery C.
Step 1
In an AVL tree, an imbalance occurs when the height difference between the left and right subtrees of any node is greater than 1. If inserting 45 causes a right-left case (where the right subtree of a node is taller than the left subtree), a double rotation is Show more…

Draw the AVL Balanced Tree that results from adding the following integers (14, 214, 33, 918, 13, 815, 134, 10, 131, 125, 45) and show each iteration. Starting with the resulting tree from Exercise 4, draw the tree that results from performing a remove root operation and show each iteration according to AVLTree remove process. Write levelOrder, preOrder, postOrder, and inOrder methods for a binary tree with and without using recursive techniques. Write a method to take a BinaryTreeNode input (root) and determine whether the given tree is a Binary Search Tree.
