It's not absurd because random tests are never the same test ... because, well, they are random. That's why your code passes a different amount of them on each run of the ATTEMPT.

and by the way I un-flagged your comment as a spoiler because it did not discuss / reveal any solution concepts / code

Your code only passes all the sample tests.

On running ATTEMPT your code is tested by multiple random tests, and it does not pass all of them.
