Otok | Island #4
Nakon što ste se vratili s otoka, odlučili ste napraviti društvenu o vašem iskustvu te se tako obogatiti. Jedan paket društvene igre ima 19 šesterokuta i jednu figuricu razbojnika. Sva pravila su jednaka kao u prethodnim zadacima.
Karlo ima neki broj paketa i od tih je napravio najveći "trokut" koji je mogao, tako da svaka njegova stranica ima jednak broj šesterokuta. Zatim je pokušao staviti najveći mogući broj figurica razbojnika tako da se međusobno ne napadaju, time postići da se ne može dodati još ni jedna figurica razbojnika. Zaključio je da to može učiniti za svoj broj paketa, a ne može za jedan paket manje.
Na vama je da otkrijete koliko Karlo ima paketa društvene igre.
After returning from the island, you decided to create a board game based on your experience and make a fortune. Each game set contains 19 hexagons and one robber figurine. The rules are the same as in previous tasks.
Karlo has some number of sets, and from them he made the biggest "triangle" he could, so that each of its sides has the same number of hexagons. Then he tried to place the maximum possible number of bandit figurines so that they do not attack each other, thereby achieving that not a single bandit figurine can be added. He concluded that he could do it for his number of packages, but he could not do it for one less package.
It is up to you to figure out how many game sets Karlo has.
