Solve the following python programming problem given the following code:
@ mark.skipif ("not hasattr(sys, 'getrefcount') == True", reason = 'sys.getrefcount() is needed to pass this test') 
def test_unpacker_hook_refcnt() : 
    result = [] 
    def hook(x) : 
        result.append (x) 
        return x 
basecnt = sys.getrefcount (hook) 
    up = Unpacker (object_hook = hook, list_hook = hook) 
    assert (sys.getrefcount (hook) >= (result + 2)) 
    up.feed (packb ([{ 
        
}])) 
    up.feed (packb ([{ 
        
}])) 
    assert (up.unpack () == [{ 
        
}]) 
    assert (up.unpack () == [{ 
        
}]) 
    assert (result == [{ 
        
}, [{ 
        
}], { 
        
}, [{ 
        
}]]) 
    del up 
    assert (sys.getrefcount (hook) == basecnt) 

    
    

    Fix the buggy line: assert (sys.getrefcount (hook) >= (result + 2))
