+# /*
+#  * EJERCICIO:
+#  * - Muestra ejemplos de creación de todas las estructuras soportadas por defecto en tu lenguaje.
+#  * - Utiliza operaciones de inserción, borrado, actualización y ordenación.
+#  *
+#  * DIFICULTAD EXTRA (opcional):
+#  * Crea una agenda de contactos por terminal.
+#  * - Debes implementar funcionalidades de búsqueda, inserción, actualización y eliminación de contactos.
+#  * - Cada contacto debe tener un nombre y un número de teléfono.
+#  * - El programa solicita en primer lugar cuál es la operación que se quiere realizar, y a continuación
+#  *   los datos necesarios para llevarla a cabo.
+#  * - El programa no puede dejar introducir números de teléfono no númericos y con más de 11 dígitos.
+#  *   (o el número de dígitos que quieras)
+#  * - También se debe proponer una operación de finalización del programa.
