#include <iostream>

using namespace std;

unsigned long long x;

short fc[10], cif, gasit=0;

int main()

{

   cout << "x= "; cin >> x;

   if (x==0) fc[0]=1;

   while (x)

   {

       cif=x%10;

       ++fc[cif];

       x=x/10;

   }

   for (cif=0; cif<10; ++cif)

      if (fc[cif]==1) { gasit=1; cout << cif << " "; }

   if (gasit==0) cout << "nu exista...";

}
