As before, line 3 doesn't execute at all since there aren't any pairs of people in the room, and so, n remains zero, which indeed matches the number of people in the room.
Kao prije, redak 3 se uopće ne izvršava s obzirom da u prostoriji nema parova osoba, i tako, n ostaje nula, što doista odgovara broju osoba u prostoriji.
