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.
Then there are two problems
a1 = ['te st'], a2 =['te', 'st']
The problem here is that it will join

This should probably be a 6 or 7 kyu problem. An experienced dev can solve this in <1 minute without having seen the problem before. Hell, I'm not experienced and I solved it in <1 minute.
All tests pass for me other than the final "basic test", which throws this error: 'It must return 90 - Expected: 90, instead got: 2'. It is unclear to me which condition is not being satisfied here. If I could see the argument for this test, it would certainly help. Please note that I have read the question and comments above to which I am replying. Unfortunately, I do not understand how the response to this question was helpful in identifying why the test does not pass. Can anyone please explain smile67's response a bit further? Any help here would be much appreciated.
Did you figure out a way to proceed with this kata?
