I like it.

Don't reinvent the wheel. <3

holy cow

Wait! Why didn't I think of this? 😅

I loved that.
Inspiring to go OOP all over every simple task just for the good practice.

but why?

Requirements:
should return 17 items
should have the correct column names
should have the correct values
should contain keywords
should contain SELECT
should contain RECURSIVE
should not contain !
should not contain CREATE TABLE

Beeing honest... I had to hardcoded it to pass it.

Helpful comment, thank you.

Well, you can use debugger while coding on your machine. Its what I do. Most of the time it requires to rewrite tests on your own, but I believe it makes me a better programmer.
Plus it will be realy hard todo for the random tests.

In this system, the last digit is always 0 and is in base 0!. The digit before that is either 0 or 1 and is in base 1!. The digit before that is either 0, 1, or 2 and is in base 2!, etc.

You can't write 2x1!

thats not a helpful response

Please re-read the description.

Wouldnt the result be ambiguous? I think i can write 2 as 1x2! or 2x1!
