Answer 1

#include <iostream>
#include <algorithm>
#include <vector>

using std::endl;
using std::vector;

int main()
{
	vector<int> vec1 = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
	vector<int> vec2 = { 5, 6, 7, 8 };
	
	if (std::includes(vec1.begin(), vec1.end(), vec2.begin(), vec2.end()))
		cout << "vec1 include vec2" << endl;
	else
		cout << "vec1 not include vec2" << endl;

	return 0;
