	int retval{ 0 };
	int value = number;

	while (value != 0)
	{
		int test = value % 10;
		if (test == 3 || test == 6 || test == 9)
			retval++;
		value /= 10;
	}
	return retval;
}

int main(int argc, char** argv)
{
	std::ios::sync_with_stdio(false);
	std::cout.tie(nullptr);
	std::cin.tie(nullptr);

	int nValue{};
	std::cin >> nValue;

	for (int i = 1; i <= nValue; i++)

		int count{};
		if ((count = check369(i)) > 0)
			for (int j = 0; j < count; j++)
				std::cout << "-";
		else
			std::cout << i;
		std::cout << " ";
