Catsfood

#3388

Anda are trei pisici foarte pretențioase, fiecare preferând un ingredient diferit din mâncarea cumpărată. La magazinul pentru animale, fiecare plic de mâncare are un cod de 3 cifre. Fiecare cifră din cele trei cifre reprezintă un tip de ingredient.

Știind că există 9 tipuri de ingrediente și că fiecare pisică are o preferință pentru un anumit ingredient, afișați:

1) Câte plicuri poate cumpăra Anda astfel încât măcar una dintre pisici să-l poată mânca?
2) Există vreun plic care să placă tuturor celor trei pisici?
