Central European Regional Contest, 1998
Welcome to the Central Europe Regional Contest Web Page. The Contest is over now! The winner is the team of Comenius University Bratislava. The second team advancing into the World Finals is Warsaw University.
There was an error in the problem cipher. The sample solution makes an invalid assumption about the cipher decryption. The same assumption was made by many (if not all of) contestants' solutions. The absolutely correct solution to this problem is much more difficult, if not even impossible. However, a very important thing is that the test data (input and output files) are correct and, thus, no correct solution was rejected!
