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.

When I tried returning integers (to see what was in the integers array in the test), it gave me:
expected:<3> but was:<[I@7d3a22a9>
It is thus not only filled with non-integers, but also it has 2 even numbers and 2 odd numbers. Unsure how can anyone resolve this.
