Implement a city database using a BST to store the database records. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x- and y-coordinates. The BST should be organized by city name. Your database should allow records to be inserted, deleted by name or coordinate, and searched by name or coordinate. Another operation that should be supported is to print all records within a given distance of a speci ed point. Collect running-time statistics for each operation. Which operations can be implemented reasonably efficiently (i. e., in Θ(log n) time in the average case) using a BST? Can the database system be made more efficient by using one or more additional BSTs to organize the records by location?
