preceded and followed by the same number of non-zero elements

That's about the non-zero elements, and you can see that in the sample test.

The description is not clear enough. The rule "preceded and followed by the same number of non-zero elements" -> does "same" refer to the zeros? Or to the non-zero groups at the beginning and end?

Very poor description, but the Kata is not bad

Approved, thanks!

Write a function named isNice/IsNice that returns true if its array argument is a Nice array, else false. An empty array is not considered nice.

How about you read the description till then end :)

I wish the feedback from the error message was clearer, as it's not clear on which exact example the code fails.

([2, 2],  0) False should equal True```

I thought that the condition says about non-empty subsequences, both "in the center" and on the edges. Wierd.
