   * <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.

В этом примере мы используем OAuth2 «password flow» (аутентификация по паролю).

Это уместно, когда мы входим в наше собственное приложение, вероятно, с нашим собственным фронтендом.
