If two producers are selling the same product (i.e. the same id), wouldn't that skew the results? I'm having a hard time understanding the difference, but there definitely is one when you compare the output tables.

Despite the condition being 2 or less in stock, "stock < 2" also passes the tests

But with my code the outcome of other test cases also results in "fractional people" but I don't see how that matters if we're looking for years. How does 1213 people differ from 1214.4 if all we're looking for is if it's > 1200?

I believe that test case expected an empty array to be returned, whereas here that'd be [0, 0], no?

I'll double-check though, I've realized my accepted solution is suspicious anyway.

Can someone please explain how this passes the [+0, +0] test case?
