Lighthouses

Lighthouses is a logic puzzle where you need to find ships hidden in a grid using clues provided by lighthouses according to some rules.

Rules: There are ships and lighthouses in the harbour basin. The lighthouses are already drawn on the map. The number in a lighthouse indicates how many ships the lighthouse lights. A lighthouse lights all ships that are in the same row or column as the lighthouse, including ships that are behind other ships or lighthouses. At least one lighthouse illuminates every ship.
Ships do not touch each other or a lighthouse, even diagonally. Draw the ships on the grid.
