    We have a lot of solutions, one of it is by solve with recursive, our initial sum is equal to value of importance, then we add other importance values from subordinates easily, sorry for poor english :)

        int getImportance(vector<Employee*> employees, int id) {        
            int sum = employees[id - 1]->importance;
            for (auto newid : employees[id - 1]->subordinates)
                sum += getImportance(employees, newid);
            return sum;
