Describe an application that uses a BST for its data collection, storage, organization, and data retrieval. Describe how you would design the functionality to use the BST$.$ The main functionality of this proposed program should use a BST as its primary data structure.

An example application that would fit into this category would be a $$dictionary$.$ The BST could be used to store the dictionary items and then the tree would be searched when someone wants to find a definition for a word in the dictionary. Suggest another application, other than a dictionary.
