#include <list>
using namespace std;
int main()
  list<int> lst1, lst2;
  int i;
  for(i=0; i<10; i+=2) lst1.push_back(i);
  for(i=1; i<11; i+=2) lst2.push_back(i);
  list<int>::iterator p = lst1.begin();
  while(p != lst1.end()) {
    cout << *p << endl;
  p = lst2.begin();
  while(p != lst2.end()) {
    cout << *p << endl;
    cout << "lst2 is now empty\n";
  cout << "Contents of lst1 after merge:\n";
  p = lst1.begin();
