The task is to print all permutations of a given string. In der folgenden Java-Lösung nutzen wir über die Tatsache, dass Strings unveränderlich sind, um zu vermeiden, das Klonen das Ergebnis-set bei jeder iteration. But there is at least one thing missing in Java for sure — permutations. A Computer Science portal for geeks. The idea is to generate each permutation from the previous permutation by choosing a pair of elements to interchange, without disturbing the other n-2 elements. ähnlich, pick-b + permutiert (ac) Provinz bac, bca...und geht weiter. Start generating next higher permutation. The first permutation is always the string sorted in non-decreasing order. permutations and it requires O(n) time to print a a permutation.
