    // in the multiset container
    s.insert(10);
    s.insert(13);
  
    cout << "The size of multiset: " << s.size();
    s.insert(13);
    s.insert(25);
  
    cout << "\nThe size of multiset: " << s.size();
    s.insert(24);
  
    cout << "\nThe size of multiset: " << s.size();
    return 0;
