Solve the following python programming problem given the following code:
def pytest_funcarg__huang_darwiche_jt(request) : 
    def priority_func_override(node) : 
        introduced_arcs = 0 
        cluster = ([node] + node.neighbours) 
        for (node_a, node_b) in combinations (cluster, 2) : 
            if (node_a not in node_b.neighbours) : 
                assert (node_b not in node_a.neighbours) 
                introduced_arcs += 1 
if (node.name == 'f_h') : 
            return [introduced_arcs, 0] 
if (node.name == 'f_g') : 
            return [introduced_arcs, 1] 
if (node.name == 'f_c') : 
            return [introduced_arcs, 2] 
if (node.name == 'f_b') : 
            return [introduced_arcs, 3] 
if (node.name == 'f_d') : 
            return [introduced_arcs, 4] 
if (node.name == 'f_e') : 
            return [introduced_arcs, 5] 
return [introduced_arcs, 10] 
dag = pytest_funcarg__huang_darwiche_dag (request) 
    jt = build_join_tree (dag, jt) 
    return jt 

    
    

    Fix the buggy line: jt = build_join_tree (dag, jt)
assistant
#Here is Python program to fix the buggy line: jt = build_join_tree (dag, jt)
