Yeah, I think the other solutions are different forms of this one. It'd be harder to figure out if you haven't studied linear algebra yet.

When I hit run, only 2 random cases are tested?

If we don't remove it the 1st option seems like the best assuming codewars allows that. In the meantime I could at least add a comment to the c++ initial code warning that it is currently not working.

Perhaps we could have an advanced version of this kata? Idk if a bigger test size is enough justification to make a separate version though

OK I'm glad I asked. Sorry for the confusion folks

Oops. Is the best way to get rid of it just to hit the X next to the language in the editor?

Man I hope y'all know what you're doing bc I'm just approving these without looking too hard at them lol

I had it at 20 earlier and Voile thought it was too high. I guess I'll have to actually develop an opinion lol. I'll also have to look at your solution since mine times out when testing 100 30-point cases.

It makes more sense to return '0', so I specified that it should do that, changed the solution, and added a test case for it. Also fixed the typo.

I went ahead and shrunk the big tests so that they're still a little bigger than they were originally. I think I'll go ahead and mark this as resolved unless I get a 3rd opinion saying it is a duplicate.

Is this really similar enough?

:o numpy

I specified that there won't be empty input (and fixed the test cases so there won't be), and changed them all to assert_equals

ok I think I fixed it
