  //if list is not empty display it
  if(list_1.empty()==false)
  {
    display_list(list_1);
  }
  list_1.sort(); //sorts the list
  list_1.reverse(); //reverses the list
  list_1.pop_back(); //deletes last element of the list
  list_1.pop_front(); //deletes the first element of the list
  
  display_list(list_1);  //function to display the list
  
  
  return 0;
}
//in addition , you can use nested lists such as list<list<int>> or list<vector<list>> etc
