Yes, this type of floating point verification is asking for such issues:

Test.assertEquals(+actual.toFixed(6), +expected.toFixed(6));

Instead, a tolerance of 1e-6 should be used.

isn't this possibly an issue?

Looks good to me. However, I tried to approve and got Failed to approve: translation must be pending over a week or the kata author must be inactive for the past month

While we're changing things, how about the parameter names? list_of_art is especially mysterious, with nothing in the problem that seems to fit the "art" abbreviation

The difference between a cat and a dog.

Seems pretty different to me

Oh i didnt know about that kata. Ig this is a performance version then.

Isnt a "not implemented" a suitable way to signal, well, a lack of implementation in the solution stub?

But it looks so much nicer 🌈

it can take time for invalidation to take into effect

Approved - Thanks!
