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.

The answer method can simply be written:
def answer(x, o)
x == o
end
If x and o are 0 (0 == 0) then the first if condition is true and so you will never get to the elsif check. Also x == o returns a boolean so there is no need to check the result in an if conditional.
