Light Up

The goal of the Light Up puzzle is to place light bulbs into cells so that all the empty ones are lit.

The "Light Up" puzzle (also known as "Akari", "LightUP" and "lanterns") is a rectangular box in which some cells are white, and some are black. The black cells can contain numbers from 0 to 4. The goal of the puzzle is to place light bulbs in empty cells so that all white cells are illuminated.

The light from the bulb is distributed in a straight line horizontally and vertically until you hit a black cell or the border of the field. Bulbs should not face each other. If there is a number in a black cell, then it must be adjacent (on the left, top, right or bottom) to a specified number of bulbs, no more and no less.
