    //appending\inserting elements at the front by push_back
    mylist.push_back(1);
    mylist.push_back(4);
    mylist.push_back(3);
  
    //print elements of  list
    std::cout << "List elements are before pop from front \n";
    for (auto it = mylist.begin(); it != mylist.end(); ++it){ 
        std::cout << *it << '\n'; 
    }

    //pop element from the front 
    mylist.pop_front();

    //print elements of  list
    std::cout << "List elements are after pop from front \n";
    for (auto it = mylist.begin(); it != mylist.end(); ++it){ 
        std::cout << *it << '\n';
