Java programs for string permutations using recursion : Program 1 : Heap’s algorithm Output Enter a String : abc [a, b, … Time Complexity : O(n*n!) All this call one library function that give permutation on index (only integers as permutation as permutations on [1], permutations on [1,2], permutations on[1,2,3] etc).So it is enough get these set of indices and build the lists; One has to note that this seems to be compiled good for every List of type X For ... , 1] [3, 1, 2] [3, 2, 1] permutations.
