Marinada '22

[lang=hr] Na kraju je Mateju ostalo još ukupno 10 zadataka na Pašticadi koje treba riješiti. Međutim, Matej (a i puno drugih ljudi) sumnja da su organizatori zapravo pripremili nešto manji broj različitih zadataka te zatim ponovili neke od njih više puta. Na koliko su to načina mogli učiniti? Konačni poredak tih zadataka nije bitan. Moguće je i da su organizatori pripremili 10 različitih zadataka (i to je moguće na samo jedan način jer poredak nije bitan). [/lang] [lang=en] In the end Matej was left with 10 more Pašticada problems to solve. However, together with many others, Matej suspects that organisers have actually prepared less then 10 different problems, and then repeated some of them multiple times. In how many ways could organizers do that? Order of the problems doesn't matter. It's also possible that all 10 problems are different (and there is only one way to do that since order doesn't matter). [/lang]
