You have been hired by a company that builds a mobile app for coffee addicts. You are responsible for taking the user’s location and returning a list of the three closest coffee shops.
The coffee shop list is a comma separated file with rows of the following form:
Name,Y Coordinate,X Coordinate
The quality of data in this list of coffee shops may vary. Malformed entries should cause the program to exit appropriately.
Your program will be executed directly from the command line and will be provided three
arguments in the following order:
<user x coordinate> <user y coordinate> <shop data filename>
Write a program that takes the user’s coordinates encoded as listed above and prints out a newlineseparated list of the three closest coffee shops (including distance from the user) in order of closest to farthest. These distances should be rounded to four decimal places.
Assume all coordinates lie on a plane.
