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.
I did not know that Java has functional patterns / iterators. Nice!
it wouldnt be complete without iterators :)
needs more iterators apparently
I found the consultant :)
risky :D
This is nice to read, but has sub-optimal performance. Every push will make a slightly bigger copy of 'vec' to keep up with size. So for n elements, the first push copies 1, then 2, then 3, ... , then n elements, resulting in O(n^2) runtime (Gauß). Dynamically sized data types are a lie.
