to clarify: this only happens with the Cuban Peso (CUP) which has denominations [1, 3, 5, 10, 20, 50, 100]. all other currencies seem to be
canonical

alright, thanks!

either you know, don't know, or know but not well enough

hm, not sure. I literally got an idea for this kata from just discovering dir()! and I suppose I would go that route if I were the one to solve

umm, sorry, I'm not too sure what you are saying. Do you want me to add some reading link in the description as a hint? I don't know which one and is it really worth..

Approved

I made my solution faulty to pass tests and checked the reference solution. It's broken: it only counts vowel substrings that are followed by a non-vowel char.

Fix:

Seeing the same thing here (Python):

Testing for 'ofimdautsiatboeueo'
Vowel substrings: ['o', 'i', 'au', 'ia', 'oeueo']
5 should equal 2

Testing for 'cree'
Vowel substrings: ['ee']
2 should equal 0

Why? What's different?

Kata notes updated. Thanks.
