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.
By using namespace std, you don't have to keep defining the "std::" prefix, so you can use "string" instead of "std::string" for the return value of the function.
It's generally not a good habit to use the entire std namespace, but in this specific case, it would have been better to replace "using namespace std;" with "using std::string;".
