Rejected the translation by mistake :-(

Here is a new fork, including an updated (language-indipendent) description.

I'm experiencing the same in Java 17; Error message mentions that the first component should have brackets in between the tags that ecapsulates the remainding output,

ex) <...le="color: orange">9[715FR329...].

the output examples states: RoboScript.highlight("FFFR345F2LL"); // => "<span style="color: pink">FFF<span style="color: green">R<span style="color: orange">345<span style="color: pink">F<span style="color: orange">2<span style="color: red">LL"

notice there are no brackets.

Ranks can't be changed

There is an open issue below about the same, please don't open another. Closing.

there is only one vowel in 'string'. str shadows the builtin function str(), string shadows the string module, people are gonna complain with either of these

BRU

Bruh!

bruh

.

You must return 0 in those cases. If it doesn't work, your code has a bug.

Don't give free hints please. Let users solve the kata by themselves (besides, there are other more efficient approaches). I marked your message with a spoiler flag.

Tests include

    mouthSize "alligator" `shouldBe` "small"
    mouthSize "ALLIGaTOR" `shouldBe` "small"

So yes it is.

Yes, fixed already, thanks everyone.
