Yes, I did the input validation, I just need to show the warning message.

| Nov 28, 2016 at 3:01 | comment | added | Drew | Why don't you suspect that it is impossible to use all zeros? What part of the question makes you think that? You might be right, but the question is not clear about what the story really is. | |
