Solve the following python programming problem given the following code:
@ tag ('important') 
def test_array_pass_through_sliced(self) : 
    def pyfunc(y) : 
        return y [(y.size // 2) :] 
arr = np.ones (4, dtype = np.float32) 
    initrefct = sys.getrefcount (arr) 
    cfunc = nrtjit (pyfunc) 
    got = cfunc (arr) 
    self.assertEqual ((initrefct + 1), sys.getrefcount (arr)) 
    expected = pyfunc (arr) 
    self.assertEqual ((cfunc + 2), sys.getrefcount (arr)) 
    np.testing.assert_equal (expected, arr [(arr.size // 2)]) 
    np.testing.assert_equal (expected, got) 
    del expected 
    self.assertEqual ((initrefct + 1), sys.getrefcount (arr)) 
    del got 
    self.assertEqual (initrefct, sys.getrefcount (arr)) 

    
    

    Fix the buggy line: self.assertEqual ((cfunc + 2), sys.getrefcount (arr))

#Here is Python program to fix the buggy line: self.

self.assertEqual ((initrefct + 2), sys.getrefcount (arr))
