I believe this fails for index == len(items), the conditional is true so it'll try to look it up but the index is out of bounds.
Using & operator with two sets creates a new set containing the elements present in both sets.

Looking at the tests, casting is apparently required
this one was an absolute blast! thank you
Practical SQL is pretty good if you're still looking

Please a little feedback would be great.
it sould be fixed now, can you try again sir?
Same confuse here, what does it mean "there's no table"? Can you specify it?

@sq6jnx re: filtering out hardcoded solutions, what about searching the submitted SQL code for the presence of all prime numbers between 2 and 100? If they're all (or some representiative subset) present in the SQL code, it fails a test?
