That makes more sense. I'll return set()

Changed to return None for no solutions case

Approved!

Thanks

Thanks! Fixed the tests to use @it decorator and fixed the titles. I also noticed that I was doing 800 assertions per batch, when I wanted it to be 800 in total.

Good idea. Just split it up.

Thanks for the suggestion. I just made batches of 100 from 1 to 10^8. (8 batches)

Thanks for pointing this out, it's now fixed.

Thanks, I'm now testing for approximate equality instead.

Changed name to reflect

Thanks, I fixed the solution.

Added this to the description.

I haven't solved that kata, but the task in this one seems quite different, as you are adding parenthesis into a string instead of removing them, where there can be many more possible outputs. This one has additional performace requirements as well.

It should now be fixed.

Thanks for the feedback, I've added these to the fixed tests.
