One problem with that:

There is no such button. I’m guessing those two buttons are unavailable on kata ranked two or more kyu above the user. Don’t think that’s stated anywhere. Is it?

Please either tell me what’s wrong with my code, or fix the kata’s evaluation code and/or instructions. Perhaps don’t have the function return an array, but pass it an array to populate.

I mean, how do you get there from the /train page? Is the site just not well laid out that way?

(Duplicate reply)

I don't see a discourse link while working on a kata.

So why are the random tests crashing on free() when I don't even call that function? How can I avoid it?

You’re most likely not using a static array for your return value. That’s needed when returning arrays in C.

I tried to edit my spoilery comment but it was just blank, so I posted this reply on that topic, and the comment suddenly re-appeared. With no edit option, though. And I don’t think I can delete this reply.

How do I comment on a kata that I have a problem completing?
