Thank you!

Hi! Thanks for the feedback! I've just taken a look and realised I was unintentionally passing the same array to the user code, as I was to the test code. (Which means if you were manipulating the array, it would affect the test result)
Hopefully I've fixed this now, could you try and submit your solution again and mark as resolved if this has fixed the issue for you?

Thanks!

Thank you!
