Delete item from QMap<int, QString> with shift

For example I want that after map.remove element with index 2 replace your index to 1..

1. #include <QApplication>
2. #include <QMap>
3. #include <QDebug>
   
4. int main(int argc, char **argv)
5. {
6. QApplication app(argc, argv);
   
7. QMap<int, QString> map;
8. map.insert(1, "some1");
9. map.insert(2, "some2");
10. map.insert(3, "some3");
    
11. map.remove(1);
    
12. qDebug() << map.value(1);
    
13. return app.exec();
14. };

You you please explain this a little bit better?

Do you want to remove the item at index 2? The item at index 2 is the item with key = "3" and value = "some3".
And do you want the item at index 2 to be replaced by the item at index 1?
