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.

So is this more efficient than using list.count 4 times?
This is wrong. The random trials do not append 0s to the end of the original array. See @Hendec 's comment
Yes, this is very broken and the instructions are unclear besides. Why 0.0 --> 0 but '0' --> '0' is beyond me.
I didn't get it at first either. The length of
signatureis getting larger and increasing by 1 each iteration. Once the length ofsignaturegrows to > n, the recursion terminates and returns all values in the now-largesignatureup to n-1. There's one extra calculation of the sum it's cool. Also handles then<=3cases nicely.Can someone explain this?
