Thx, I prefer let you do the job, too many years I was away from here.
Have fun !

Hahaha, as in ruby reference kata :))

Well, in my opinion it wasn't an issue to simply say there is a "10" in a card pack, but If it bothered you, it may bother someone else so I change the description.

Happy Coding ;)

Actually the first line just shows what a "standard 52-card pack" should be.

The second line explains how these cards will appear in arguments (with a "T" standing for a "10").

Is it the inconsistency you're talking about ?

Are you still thinking this as an issue ?

Sorry, you're right about description.
Concerning the 'aaAA11@@--' case my solution doesn't mark it as valid.

Where it's said "-" is not a valid character ?

Description says :

return true if the walk the app gives you will take you exactly ten minutes (you don't want to be early or late!)

Happy Coding!

Ja Ja Ja . . . insane Ka Ka Kata ! ! !

muhahaha ! ! !

Nice !

Description says :

... and returns this string with word S in it eventually converted to their "pig-sursurunga number type".

...also :

EACH group of number+space+word found in the string should be evaluated.

... and examples :

  sursurungal('5 lions and 15 zebras') // -> '5 lionzo and 15 gazebraga' (paucal and plural)
