Suppose you have a ?le orase of city and country names, like this:

Cluj, Romania
Debrecen, Hungary
Klagenfurt, Austria
Berlin, Germany
Szeged, Hungary
Budapest, Hungary
Lintz, Austria

Write a program towns.pl such that when it will read from the ?le orase will produce a sorted output with each country mentioned once, followed by an alphabetical list of the cities in that country:

Austria: Klagenfurt, Lintz.
Hungary: Budapest, Debrecen, Szeged.
Germany: Berlin.
Romania: Cluj.

Run your program against any other ?le (say, myfile) with structure similar to orase. Then execute your program against both ?les (orase and myfile) simultaneously.
