Question 3 AVL Trees [5 marks]
Delete the node with key 14 from the following AVL tree, performing all necessary rotations so that
the tree maintains its AVL property after deletion. After performing each rotation, draw the tree
after that rotation and indicate clearly what rotation was performed by writing something similar to
Rotate left on Node X. Treat a double rotation as two individual rotations. If no rotations are
necessary, simply draw the final tree and note that explicitly.
