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.
The point was to hand-write a recursive function :)
If you're sorting by itself, cant you just do
.sortedinstead?You probably don't want to use
(def)within adefnlike that. I believe it'll conditionally polute the namespace. If you never call it,all_pointsandaveragewon't be defined on the namespace (which is good), but if you do call it, they will be defined on the namespace. Consider usingletinstead.
