Wow, so many 1 kyu code warriors defending a dead horse here. Yet the tests are inconsistent with the description.

If the polling rate is 100 ms and the operator takes 110 - 170 ms per dot or short break, how can a 200 ms break be considered a long break (dividing letters) if it should be 3 dots long (which would be 330 - 510 ms]? Yet somehow, "1001" should be translated as ". ." as per tests, thus resulting into "EE" where "I" would be more consistent with the tests.

Yes, you can come up with a solution that passes the tests without hacking any leftovers, but it doesn't solve Morse code. It solves some mathematical problem that is carefully hidden out of the description so that people with at least Bc. of theoretical mathematics can figure it out.

should be good now. Reset the trainer and try again

Thats the point

Not a kata issue.

But... this is what the kata is about? It's your task to determine how long are sequences for a dash, dot, short gap and long gap.

This kata might have some issues, but the part you are complaining about is not one - it's the whole point of the kata.
