Write a program that starts off with an empty Data object. Then your program should start reading in uppercase characters. Each character will correspond to a command and some commands will have arguments while others will not. If a command has an argument, it will follow the character on the same line, separated by a space. The commands are as follows:

A r - add a circle of radius r to the Data object

R i - remove the object at index i from the Data object

S - sort the Data object

P - print the Data object

D - destroy the Data object

Q - terminate program
