Listing 3: Antwort von ChatGPT auf Aufgabe 3 (RegEx)

^(?=(?:[^0-9]*[0-9]){2})(?=(?:[^A-Za-z]*
[A-Za-z]){2}).{6}$
Dieser Ausdruck bedeutet:
^ und $: Anfang und Ende der Zeichenkette.
(?=(?:[^0-9]*[0-9]){2}): Ein Lookahead, der
sicherstellt, dass mindestens zwei Zahlen
vorhanden sind.
(?=(?:[^A-Za-z]*[A-Za-z]){2}): Ein Lookahead,
der sicherstellt, dass mindestens zwei
Buchstaben vorhanden sind.
.{6}: Genau sechs beliebige Zeichen.
