-The interesting bits are in the following methods:
-
-- `updateBalance()`. Called after inserting a new node. This may cause the node's parent to be rebalanced.
-- `rebalance()`. Figures out how to rotate the nodes to restore the balance.
-- `rotateRight()` and `rotateLeft()` perform the actual rotations.
+The interesting bits are in the `balance()` method which is called after inserting or deleting a node.
