#include <iostream>
using namespace std;


int main()
{
    for (int i = 10000; i < 100000; i++)
    {
        int j, t;
        j = 0;
        t = i;
        while (t)
        {
            j = j * 10 + t % 10;
            t = t / 10;
        }
        if (i << 2 == j)
        {
            cout<<i<<endl;
        }
    }

    return 0;
}
