Other languages see no change, it's just that LC needs some additional info. It's in an if-block. ( If you go to the translation Diff tab, you can see the changes. )

does your addition change the description on Python, C, Haskell, etc.? or does it appear only on the LC description?

this tests check that you haven't changed the input data. are you returning a new array?

somebody can help me?
so i try mi code in google colab and the answer its okay, but in my test the program says me "the function give [2,2,1,2,2] and should be equal to [2,2,2,2,2] but when a run in colab this same example the program its right.
