What pattern would be different in the random tests?

I solved it in a similar way without opening google.

Damn, i had the same issue. thanls for clarifying

2024 is smaller than 2177.

Or that you haven't looked at the language version and realize that it's PostgreSQL, not mySQL.

If you're trying to write SQL queries without first looking at what flavour you're writing your queries with, then well...

No problem, and you could check how to proper format your code in a comment for future reference, it makes it more readable (otherwise all indentation is gone). Good luck.

It's more like nothing squared is the same as nothing (both are empty arrays).

Try writing console.log(array1, array2); as the first line of your function, see which test is failing and why (when you click attempt).

Try using console.log() with the parameters you want to check. Read the remarks in the details.
