True, excellent Kata, your hint should be included in the description.

Thanks

Scala translation

Your solution is too slow, you need to find a different method rather than calculating the full factorials.

Fixed (based off Python version since those tests looked cleanest).

JS tests broken

Nice kata!
Little hint: when you understand how to calculate it without having to find the factorial of two parameters separately, everything will become pretty straightforward

Unexpectedly light kata as for 6 kyu

Nice kata!

IMO there should be another 2 or 3 digit number in the examples. You can very easily get a pattern that works beautifully with the displayed cases, but then falls apart on the attempt. Took me a minute, but this was a really fun problem.

Appoved! Thanks +1

updated Ruby translation kumited -- please check and approve :-)

little hint, think outside your calculator base number

I need a small hint.
Is the puzzle logic related to the function name "oneTwoThree"?

Yes, thanks, I got it.

"Substrings will be in decreasing order of their length and when they have the same length sorted in ascending lexicographic order"

In what order should it be sorted?
