What do the failing tests say?

On console the result is totally correct but few arguments are showing wrong in the result board.
I tried to match the length, and they matched.

Which tests are failing?

Am I missing something?

ohhhh! I see now…
thanks for your time.

:+1:t2: Good job finding it on your own.
