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.
My solution is less clean and too verbose, but it does not require standard 11/14/17/20, also 15% faster then tuple/pair.
In your solution i would use a pair instead of a tuple:)

If there weren't extra spaces, the test would pass, no?
try adding:
std::cout << "'" << your_result << "'" << "\n";at the end of you function.
