Japanese Parking Lot (935)
Instruction:
Locate some automobiles in the grid. Automobiles have a 1×2 or 1×3 shape, do not overlap each other, and can be oriented horizontally or vertically. Each automobile contains exactly one given number. The number in the automobile represents the number of other positions the automobile can "drive" to along its long direction without overlapping with another automobile (that is, the number of empty cells directly ahead or behind the automobile’s length-1 edges).
Numbers outside the grid, when given, indicate the sizes of all continuous groups of automobile-occupied cells along that row or column, in positional order. These groups are separated by unoccupied cells. A question mark (?) indicates a group of unspecified (but non-zero) size.
