/*
* No arquivo PDF tem um requisito que diz o seguinte:
* You can assume that the initial tournament is well-formed (that is, there are 2^n
* players, and each one participates in exactly one match per round)
* Portanto, eu não considerei no código que o torneio pudesse ter 3 ou 5 chaves de torneio (TournamentBracket), por exemplo.
* Há um teste unitário validando o resultado proposto pelo arquivo pdf.
*
* O jogo pode ser executado e testado via console ou pelo projeto Tests.
