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.

Use something like bubble sort but make it sort not-zeros and zeros.
Anything which is not an object type such as maps, arrays, object literals are not allowed. You can create variables of primitive types such as numbers or may be even string
The constraints were meant to limit the space complexity to constant which is definitely useful in memory-constrained platforms such as embeded systems or even in a large scale data streaming application which can't store everything in the memory.
