WebThis is a Java Program to implement AVL Tree. An AVL tree is a self-balancing binary search tree, and it was the first such data structure to be invented. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. WebRR Rotation. If the node is inserted into the right of the right sub-tree of a node A and the tree becomes unbalanced then, in that case, RR rotation will be performed as shown in the following diagram. While the rotation, the node B becomes the root node of the tree. The critical node A will be moved to its left and becomes the left child of B ... black schnauzer puppies for sale
