    greek_gods = greek_gods->insert(new Link("Mars"));
    greek_gods = greek_gods->insert(new Link("Poseidon"));
    
    Link* g = greek_gods->find("Mars");

    Link* n = norse_gods->find("Zeus");
    if (n == norse_gods) norse_gods = n->next();

    n->erase();
    greek_gods = greek_gods->insert(n);

    cout << "======================" << endl;
