using std::cout;
using std::endl;

int main()
{
	list<int> lst{ 1, 3, 8, 23, 88, 12, 99, 7 };

	list<int>::iterator pos;

	pos = find(lst.begin(), lst.end(), 88);

	list<int>::const_reverse_iterator rpos(pos);

	cout << *rpos << endl;

	list<int>::const_iterator pos2;
	pos2 = rpos.base();

	cout << *pos2 << endl;
