My (Kotlin) function returns a string after using .trim() on it.
I'm always failing a test from randomTests due to inconsistent trailing/leading space requirements.
Here are some instances of running the full test suite, without changing my code (all other test categories are passed):

expected:<...WEp Ee AvYrylSO nb l[ ]> but was:<...WEp Ee AvYrylSO nb l[]>
expected:<[ ]FFSfWTtMT A rFDgHqe ...> but was:<[]FFSfWTtMT A rFDgHqe ...>

Is anyone else having issues getting array functions to link? I had to separate them all into individual lines because doing something like
.split("").reverse().join("") failed with an error saying you can't link them. Thanks!
