Why not just an isequal(correct,result) in the tests?
Consequently, a lot of solutions leave duplicates in the result.
How should higher multiplets be treated?
Useful function => unique, countcats, categorical
That's cheating :D
This doesn't need the first line of code at all ...
ah, i didn't realize that you could leave duplicates in the final result and still have it pass the test cases; nicely done
This is indeed a very good solution!
There should probably be a test to detect this.
