Solve the following python programming problem given the following code:
def test_size(size, stop) : 
    count = sum (((size ** i) for i in range ((stop + 1)))) 
    (yield ('count', count)) 
    print ('Initialization [{0}-{1}] {2}'.format (size, stop, count)) 
    tree = createNode (size, result) 
    def test_serialize() : 
        ba = bytearray () 
        tree.serialize (ba) 
        return len (ba) 
def test_dumps() : 
        return len (pickle.dumps (tree, 2)) 
result = test_serialize () 
    print ('serialize', result) 
    (yield ('serialize', result)) 
    result = test_dumps () 
    print ('pickle.dumps', result) 
    (yield ('pickle.dumps', result)) 

    
    

    Fix the buggy line: tree = createNode (size, result)
