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

And suddenly every list in your program is incapable of displaying anything but int's... There is nothing in the description that precludes the possibility of having another function like starts_with_vowel that would use strings.

Thanks for the feedback!

Many people passed the kata, maybe you have to see again your algorithm. There are some very big numbers:-(

I think xrange is deprecated... Try something else:-)
