What will be the output of the following C++ code?

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
int main(int argc, char const *argv[])
{
	vector <int> v = {90, 47, 34, 23, 4, 35, 67};
	auto it = is_heap_until(v.begin(), v.end());
	for(auto i = v.begin(); i != it; i++)
		cout<<*i<<" ";
}
