Rules: Place a lightbulb into some cells so that all cells in the grid are illuminated. Lightbulbs illuminate orthogonally adjacent white cells, until the rays meet a black cell or the edge of the grid. Lightbulbs must not lighten each other. A digit in a cell indicates the number of the lighbulbs that are orthogonally adjacent to that cell.
Solution code: For every row from top to bottom enter the number of lightbulbs.
