   * <p><i>Notes:</i> This is an implementation of the algorithm for Lexicographical Permutations
   * Generation, described in Knuth's "The Art of Computer Programming", Volume 4, Chapter 7,
   * Section 7.2.1.2. The iteration order follows the lexicographical order. This means that the
   * first permutation will be in ascending order, and the last will be in descending order.

    /*
     * Don't bother testing. All non-primitive parameters are used only to construct error messages.
     * We never want to pass null for them, so we haven't annotated them to say that null is
     * allowed. But at the same time, it seems wasteful to bother inserting the checkNotNull calls
     * that NullPointerTester wants.
     *
     * (This empty method disables the automatic null testing provided by PackageSanityTests.)

    * Durch die Verwendung von FastAPI sparen Sie also Entwicklungszeit, Fehler und Codezeilen und würden wahrscheinlich die gleiche Leistung (oder eine bessere) erzielen, die Sie hätten, wenn Sie es nicht verwenden würden (da Sie alles in Ihrem Code implementieren müssten).
