Hey guys I really enjoyed the short contest this month and though I would solve 2 problems for sure but it seems that my code for ALETHIO has a bug which I wasn't able to correct in time, and still can't identify. Maybe another set of eyes will be able to help me out. I was thinking maybe the problem could be in the index I was using to check previous elements or the fact that I use a boolean variable but never set it false, but I haven't been able to come up with cases that verify this. Thanks in advance for any insights. :)
