Filling by Phil15 - This will end on Maya Island. You have a rectangular grid with digits. You have to fill the grid with digits in such a way that each connected region (diagonally separated squares are not adjacent) of identical digits has an area equal to that common digit.

filling([[0, 2, 0], [0, 0, 2], [0, 1, 0]]) == [[2, 2, 1], [3, 3, 2], [3, 1, 2]]
