I am having an issue with the solutions test in swift. I am getting 1 more than the expected value.. Meaning that it's probably an issue with the range I am using but I don't think so since all the example tests and random tests have passed successfully with the expected amounts of possible answers. Is anyone having the same issue?

I posted how I found my range bellow if someone could please shed some light as to what I am doing wrong exactly.

Thank you!

Well inferring that equation from the description is part of the kate imo.

That was my initial approach but I didn't know it was allowed to write another function.

Wow can't believe I didn't see what I forgot to add but cheers man!

Alright thanks for the hint!

I used that and something more.

They worked for me.

Tests using swift not working? Code works fine on playgrounds
