This function is invoked by add_node and remove_node. p points to the first node that we need to check for possible height update. We then need to check possible height update toward root. All nodes whose heights need to be updated will be performed in this function. When invoked, action_node_pointer = nullptr, pattern = 0. If no imbalance is detected, action_node_pointer remains nullptr, and pattern [Show More]
