This contest is another of the Surprise / Unknown Language Round of series. In such rounds, participants solve problems in only one programming language, which is not available in regular rounds and is unknown to most sports programmers. The language is announced at the beginning of the contest, after two hours you need to master it and apply it to the tasks (relatively simple and not requiring advanced algorithms). Last rounds featured Tcl, Io, Pike, Befunge, COBOL, Factor and Roco. I hope that the language of this round will be the same surprise as all previous ones.
