Soccer Challenge

Write an application that will use the information files to display the soccer clubs that correspond to a set of comma-delimited country codes that the user enters. You need to create the two files from the Country (country.csv) and Soccer Clubs (clubs.csv) sample data below.

Things to note

The order of the results is not important.
You can assume that the comma-delimited list of country codes entered by the user never contains whitespace, and that the country codes entered are always upper case.
You can assume that Countries.txt will never contain any repeats of country names and codes.
You can assume that Clubs.txt file will never contain any repeats of club names.
You can assume that both text files will always be encoded as US-ASCII;
Your implementation doesn’t need to worry about performance.

Country Sample Data

South Africa, ZA
Brazil, BR
United Kingdom, UK

Soccer Clubs Sample Data

Pirates, ZA
Sundowns, ZA
Chiefs, ZA
Coruripe, BR
Commercial, BR
Man Utd, UK
Chelsea, UK

Example 1

For example:

When the user enters the comma-delimited set of codes “ZA,BR”, the program will display all the clubs corresonding to both South Africa and Brazil.

Pirates
Sundowns
Chiefs
Coruripe
Comercial

If there are no clubs that correspond to the country codes entered, the program will display No Results.
