Fill the grid with digits 1 to 9 so that each row, column and boldly outlined box contains each digit exactly once. Each gray line has exactly one thermometer bulb. It is possible that the bulb is not placed on an endpoint of the line. In that case, you get two thermometers starting from the bulb. Digits inside thermometers have to be in increasing order starting from the bulb.
Solution code: Row 5, Column 4
