Each database record contains the name of the city (a string of arbitrary length) and thecoordinates 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, deletedby 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 specifiedpoint. Use following two classes:struct city{/* add the city attributes and pointers to left and right child nodes*/}class CityDB{/* create a BST for a City Database here in this class */}Note: The distance formulais > \«: «-w »* , where x1y1 are coordinates of city 1 and x2, y2 are coordinates of city 2. 2.Create the same City Database that you created in the first question using Hash table.
