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

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
int main () 
{
    int myints[] = {1, 2, 3, 4 ,5};
    vector<int> v(myints, myints + 5);
    v.push_back(33); 
    push_heap (v.begin(),v.end());
    cout << v.front() << '\n';
    sort_heap (v.begin(),v.end());
    return 0;
}
