Is 'producent' a common word in Indian English or something? I understand part of learning SQL is figuring out how other people have designed tables, but this is only a 7kyu.

You can filter for debugging kata

I will also try to play ChatGPT )

No, 7kyu is the correct status. This kata is one of the reasons why ChatGPT is not a good developer.

Not a kata issue.

Okay, so it pays to look at the examples and fully understand them. I thought the survivors of each attack were the difference between the two sides (so like 4 attackers and 2 defenders, attackers scored 2). But it's really asking how many waves were survived. I was reading the numbers as number of soldiers, but I should've been thinking of it as the attack power of 1 soldier.

I'm getting error that i don't understand:
None should equal True

And
None should equal False.

also, i have a case where I’m returning False within the code (confirmed entering the loop using a print statement). However, it is stating True

There is no test with both None. There is a test with both empty lists tho.

All right, I think this is dumb. If A OR b is none, return False, but if they're BOTH none, return True? The instructions don't say that anywhere that I saw.

In Python, for the fifth test, the arrays seem to be empty but it says:
False should equal True

Are they not empty? Are they weird somehow?

Thank you. I like debugging ones.

And... solved! Thank you.

I think this should be 7kyu.

If you figure that out, you will pass this kata.
