I have been an editor and co-author of several books that contain statements and solutions to many problems from Polish programming competitions. For three of them I had the pleasure to work with my team of editors from the University of Warsaw: Prof. Krzysztof Diks, Jakub Łącki and Jakub Radoszewski.
You can also check out my detailed contribution to these books.
