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.

May be it is problem in random generated string in tests
No, because if I put this string in test sample I have expected result 23
I have a solution(Ruby language), but one test in test suite failed.
I logged text and saw this "wVAPVv0IRsGGmCJiM0teT5F1StS7qqIayzLGQcBp4DPCIKMl0sGquKvEgX4C5oiiFFHTbLT5H4pQxukA9lvCiAVmQjo86LUEP"
It should(according test) returns 0, but in my solution script returns 23(and it is right)
Is it problem in my solution? or something else?
whithout 'bigdecimal' I have NaN when n > 170
will try
