Using global variables for kata state is Bad Design(TM). Please use a proper class to encapsulate the entire operation.

with a 2-Down-1-Up procedure, one needs to give the correct response twice before the task can become harder

It's not clear how subsequent correct responses interact with 2D1U. Does it take 2 more responses before the task become harder again? Or does it go harder again each response.

Also, sometimes description writes D12U when it should be 2D1U.

Ruby 3.0 should be enabled, see this to learn how to do it

Done.

Python 3 should be enabled.

Ah ha! Yes, the verbs used by the generator were not all in present tence. Fixed, thanks!

Changing entered to enter and responded to respond should do the trick ;)

I see. I didn't do the ruby translation, and the js seems to work fine. You seem to be a lot more useful than me at potentially fixing this. Could you suggest a way?

It's a mistake in the random test data. Check the verbs array in the ruby translation tests cases: verbs.grep(/ed$/) =>["entered", "responded"]. It should only contain verbs not already ending in ed.

Hi ojundt, thanks for your message. I can't replicate the error you have. Are you sure you are not defining any global variable?

There are random test failures when input starts with Today I didn't entered or Today I didn't responded (which looks incorrect anyway). Example test: It should work for random inputs too - Expected: "I don't think you didn't entered the fireman today, I think you did entered it!"

Managed to?

Thanks for the feedback

Yup, it worked today!

No, the answer is not an empty string. Something went wrong at CW, the servers seems much slower than usual. Maybe you could give another try?
