样题2

Veebee's department store occupies five of the six floors in a building. On the remaining floor is a restaurant. The floors are numbered one through six, with the first floor at the bottom and the sixth at the top. Veebee's has four departments: housewares, kids, furniture and clothing. Each department occupies a separate floor except the clothing department, which occupies two adjacent floors.

The kids department cannot be located on a floor immediately above or immediately below a floor occupied by the clothing department.
