Tents (Double) (1064)

Place tents into the empty cells in the grid. Each tent occupies two cells that share an edge. Different tents may not overlap or be in cells that share a corner (or an edge). The tents and trees must match up in such a way that each tent matches one tree. A tent must occupy a cell that shares an edge with the cell of its matching tree. (It is permissible for a tent’s cells to share corners or edges with non-matching trees.) Some rows and columns may be numbered. A number indicates the number of tents that occupy cells in that row or column.
