Ambiguity in problem description

  • 0

    Question about test case:
    It is said that the right answer for this case will be
    That is confusing, because if we say that elements '-1' (first in array) and '-1'(5th in array) are different( that is why we have sub array[-1,-1,2] in the answer) the real answer must be the following
    [[-1,0,1],[-1,0, 1],[-1,2,-1]]
    because we have different "-1" in array.
    Please correct test cases or refine problem description to avoid ambiguity.
