Dieses Rätsel war ja eine höchst erfreuliche Überraschung für mich! Egal, was ich eigentlich vor hatte, da musste ich ja gleich mal ran :-).
In der Lösungscodebeschreibung ist hinten "von links nach rechts" gemeint.
@CHalb: Merkwürdigerweise war der Fehler in der englischen Verison nicht vertreten, da muss ich hier beim Erstellen wohl irgendwie geistig abwesend gewesen sein :D
