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.
All my solutions presume there were no circular routes. Is this correct?
Here are 2 examples:
1- [("NewYork", "Paris"),("Paris", "NewYork"),("NewYork", "Frankfurt")] returns "Paris, NewYork, Frankfurt".
Should the actual result be "NewYork, Paris, NewYork, Frankfurt"?
2- [("NewYork", "Paris"),("Paris", "London"),("London", "NewYork"),("NewYork", "Frankfurt")] returns "Paris, London, NewYork, Frankfurt".
Should the actual result be "NewYork, Paris, London, NewYork, Frankfurt"?
