Hi f.rodrigues,

My solution works on the simple test case then when I try to submit I get:

Passes on Invalid puzzles
Passes on Unsolvable puzzle
Passes on More than one answer
Fails (I think) on Should solve an easy puzzle - not sure, if this is the same as the first test case then I should pass

This is as far as the output goes but I get a StdError suggesting that my code does not handle this last test case.

Are you able to share this last test case?

Thanks

OK thanks. That did it.

Confused:

I pass 90 tests with no failures in <400ms yet I get
this STDERR:

-c:29: RuntimeWarning: divide by zero encountered in long_scalars

with no further explanation (i.e. there is no indication of the
input that fails the test). I am suspecting that it's a precision problem
for larger integer inputs but haven't figured this out yet.

Any guidance?
