List <integer> Results = new arraylist <integer> ();
For (INT I = 1; I <= 4; I ++)
{
For (Int J = 1; j <= 4; j ++)
{
If (I = J)
{
Continue;
}
For (int K = 1; k <= 4; k ++)
{
If (I = k | j = K)
{
Continue;
}
Int num = 100 * I + 10 * j + K;
Results. Add (Num );

    }
    
   }
  }
  System. Out. println ("the number of conditions is" + results. Size ());
  For (INT I = 0; I <results. Size (); I ++)
