NettetTree (a) is an AVL tree in Python. In tree (b), a new node is inserted in the right sub-tree of the right sub-tree of the critical node A (node A is the critical node because it is the closest ancestor whose balance factor is not -1, 0, or 1), so we apply RR rotation as shown in the tree (c). Note that the new node has now become a part of tree T3.
