Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

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?
