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.
I'm sure this solution works for all the test cases, but what if another data type such as array, hash or boolean was passed to this function? Didn't the problem specifically ask for an error message in response to a string?

Gotta say I don't entirely understand what I did here, but I think I learned something? This should definitely be higher than 7 kyu.

I like this! Though I'd suggest not mutating the input.
I had this issue also. Switching the language version allowed me to complete the kata.
"Motive" (see also: "motif") is correct - there are no movies in this kata. This is in reference to the artistic theme or subject of the photos.
