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 don't know if you've solved it yet, but you just have to throw an exception, any.
The Interpreter can continue after that.

No, time complexity is still
O(n * (n + n + n)) = O(n²).So should I throw a RunTimeException? If I thow, how can I make interpreter be able to continue accepting input.
I am shame about my 70 lines code :p
Can someone explain "[\s]+(?=[^'](?:'[^']'[^'])$)" for me? Thanks a lot!

Beautiful code, learned a lot, well done!
Beautiful
Concatenating strings with += in a loop can have a time complexity of O(n^2)!!!!
Adding this all together, the overall time complexity is O(n^3).

oh...
lol
UNION removes duplicate records (where all columns in the results are the same), UNION ALL does not.
