Place the digits 1 or 9 into each square so that the
eight different 4-digit numbers reading across and down are in
increasing numerical order, as indicated by the numbers outside the
grid. For example, the row or column indicated with a 1 is the smallest
4-digit number, followed by the row or column indicated with a 2, and
so on.
