#include <iostream>
#include <cmath>
using namespace std;
int main() 
{
    int i, j;
    for (i = 1000; i < 10000; i++)
    {
        j = sqrt(i);
        int g = i % 10;
        int s = i / 10 % 10;
        int b = i / 100 % 10;
        int q = i / 1000;
        if (q == b && s == g && i == j * j)
        {
            cout << i << endl;
        }
    }
    system("pause");
    return 0;
