Consider using a small tolerance for the solution. My program coincides with your test cases up to 3e-16. That ought to be good enough, I think :)

My solution error was at 2.22e-16. Still not good enough, though.

it would be useful to say that you want solution in integer! (althougth I do not understand why)

Obviously round(A\b) is the alledgedly correct answer which is in general different from the numerical approximation of the solution.
I wonder whether this is intended?

Assumes the solutions are always integers. The tests would ideally use a tolerance in checking the solutions.
