  1. - Push (Element hinzufügen): Fügen Sie ein Element oben im Stapel hinzu.
  2. - Pop (Element entfernen): Entfernen Sie das Element von oben.
  3. - isFull: Überprüfen Sie, ob der Stapel sein Limit erreicht hat (in diesem Fall 10).
  4. - isEmpty: Überprüfen Sie, ob der Stapel leer ist.
  5. - Anzeige: Zeigt die Stapelelemente an.
