int main()
{
	std::list<int> lst;
	std::mt19937 gen(std::chrono::system_clock::now().time_since_epoch().count());

	for (int i = 0; i < 10; i++)
		lst.push_back(i);

	std::vector<int> vec(lst.begin(), lst.end());
	std::shuffle(vec.begin(), vec.end(), gen);
	lst.assign(vec.begin(), vec.end());

	for (auto i : lst) {
		cout << i << " ";
