Hello Codeforces! Are you ready for the third Universal Cup stage made of problems from Potyczki Algorytmiczne? I hope so, because during the next weekend (21.06-22.06) you will have a chance to participate in it!

Please note, that this is the last stage in this season and your last chance to participate!

The contest, just like the previous two (1, 2), is composed of problems from the finals of Algorithmic Engagements, the biggest polish open programming competition. If you happen to know the problems from the last two finals, please don't participate in this stage.

Problems used in the upcoming contest were authored by me (Radewoosh), Marcin_smu, tribute_to_Ukraine_2022, fwitt, onufryw, mnbvmar and Markadiusz.
