Solve the following python programming problem given the following code:
@ testing.for_all_dtypes () 
def test_non_contiguous_array_stream(self, dtype) : 
    def non_contiguous_array(xp) : 
        return testing.shaped_arange ((3,), xp = xp, dtype = dtype) [0 : : 2] 
self.check_get (<MASK>, self.stream.ptr) 
    
    Given the code above, what is a proper replacement for <MASK>?
assistant
#Here is a proper replacement for <MASK>.
