The computational complexity of some problems grows rapidly with input size and sometimes trivial, nave solutions pass for small inputs, but are not sufficiently performant for more challenging scenarios. After you have added a few kata to a collection you and others can train on the kata contained within the collection. Such a situation means that solution does not pass all the tests. ''' Get started now by creating a new collection. This leads to the fact that whatever you print in your solution will appear above the assertion message it applies to. When you see only one failed test and nothing after it, that might mean that its the first test which your solution failed and once you fix it, there are more to come.
