Vova bought a ticket in a tram of the 13th route and counted the sums of the first three and the last three digits of the ticket’s number (the number has six digits). It turned out that the sums differed by one exactly. "I’m one step from happiness," Vova thought, "either the previous or the next ticket is lucky." Is he right?
