using namespace std;
 
void isDivisible(long long int n)
{
    long long int temp = n;

    int dig = 0;
    while (n) {
        n /= 10;
        dig++;
    }
    if (dig == 4) {
      while (temp) {
          int k = temp % 10;
          if (k%2==0) cout << k << '\n';
          temp /= 10;
      }
    } else cout << "No\n";
}

int main()
{
    long long int n = 1234;
 
    isDivisible(n);
 
    return 0;
}
