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.

Ahh you're right :) my mistake
There's a small mistake in the description section of the python translation of this kata:
Example subsequence
Subsequences of "abc" = "a", "b", "c", "ab", "ac", "bc" and "abc".
"ac" is not a subsequence of "abc" :)
Hey :)
I've added random tests now - sorry about before I really misunderstood what was meant by random! Let me know if you think the test-cases help the strength of the kata - I'd love to get it published. I can keep investigating more efficient solutions too.
Thanks for the feedback guys!
I've added some more random tests, including tests with longer keys (including some keys that are just symbols). I also added a description of how to handle empty-lists and empty dictionaries (they can exist in the nested structure, but only as values / endpoints because they aren't hashable (in python, at least). Does this help the kata, in your opinion? What more should I add if I am (stubbornly) hopeful that it will get published?
