That is *irrelevant*. The items *there* do not need to be different and can
even be ordered. It is just the data base for subsequent (pseudo-)random
selection; it suffices that the *key* for accessing that array is a
(pseudo-)random number, and if key repetitions are to be avoided, that you
remember which keys have been used.

Sorry, you are posting in gibberish even for a native speaker of German who
could, in theory, try to guess what you meant in English by translating that
word-by-word back to German. But in practice, with what you posted this one
cannot. Therefore, I strongly suggest you stop posting in English until you
improve your English so as you need not rely only on online translators.
