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

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
void Display(const vector<int>& vi)
{
    for (size_t i = 0; i < vi.size(); ++i)
        cout << vi[i];
    cout<<endl;
}
int main()
{
    vector<int> vi;
    vi.push_back(3);
    vi.push_back(5);
    sort(vi.begin(), vi.end());
    Display(vi);
    while(next_permutation(vi.begin(), vi.end()))
    Display(vi);
    return 0;
}
