#4050

În jocul Among Us un echipaj încearcă să piloteze o navetă spațială. O parte din ei încearcă să saboteze misiunea. Acești „impostori” sunt de obicei periculoși și astfel astronauții (sau „crewmates”) trebuie să se ferească pe cât posibil de aceștia. Astronauții au studiat planul interiorului navetei și au constatat că este compartimentat în nxm cabine, dispuse pe n rânduri, câte m pe fiecare rând. Ei au creat o matrice a codurilor asociind fiecărei cabine un număr din mulțimea {0,1,2}. Ajutați echipajul marcând fiecare cabina sigură și accesibilă din navetă!
