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.

Guys help me please! I pass through basic test and fails when I think it try to test City with no inputs.
so if no mathches i said "if(!$isIn) return -1;"
But when run - the next output comes "Failed asserting that -1 matches expected 1.6083333333333332."
Ok , I think , I will add 1.6083333333333332 in return - this one I get "Failed asserting that 1.6083333333333332 matches expected -1."
