You're wrong there, aeiou are vocals, not consonants and are never treated as consonants. See the examples in the description again.

I can't understand what is the problem asking for because it some time deals with aeoui as consonants and some times no

Duplicate issue.

Thanks!

First hour 30 dollars + 3 and half hours more, at 10 dollars each half hour gives you 7 * 10, 70 dollars. 30 + 70 = 100

same with me, still stuck in this situation, how can 273 min cost 100 dollars, where 273 mins = 4 hrs 33 mnt.
1 hours = 30 dollar,
4 hours = 120 dollar?

your update message: but why? i have the same problem and i don't get it :(

OP solved it, closing

I don't think there's only one correct way of calling it, as they both refer to the same thing: "Regular Expressions".

Thank you so much for the formula.

RSpec in the Bash version uses expect(output).to include("Value is 00005"). A substring check is imprecise and opens the door to false positives. eq() instead of include() fixes the issue.

found the bug in the random tests -- it now spits correct arrays

no prob
