using namespace std;
int main(){
	int n,k;
	cin >> n >> k;
	vector<int>a;
	
	// write your code here......
	for (int i = 0; i < n; ++i)
	{
		int num;
		cin >> num;
		a.push_back(num);
	}
	for (auto it = a.rbegin(); it != a.rbegin() + k; ++it)
	{
		cout << *it << " ";
	}
	return 0;
}

使用反向迭代器反向输出即可。
