Nov 21, 2010 · What is an elegant way to find all the permutations of a string. E.g. permutation for ba, would be ba and ab, but what about longer string such as abcdefgh? Is there any Java implementation example?

Aug 11, 2012 · I'm trying to find permutation of a given string, but I want to use iteration. The recursive solution I found online and I do understand it, but converting it to an iterative solution is really not

Jan 9, 2015 · This solution assumes that the original string does not contain duplicate characters, otherwise the permutation maps Map<Integer,String> should be used instead of the permutation arrays String[]. The reduce method takes a pair of permutation arrays and sums their elements in pairs, accumulating the results.

Nov 3, 2014 · So to permute a string that has n characters, we need to pick each of these characters, decide that it is the first, and then attach all the permutations of the remaining string to this first letter. This means we have to find all the permutations of a string that is n-1 characters long, and append it to the first letter we chose. So,

Mar 4, 2016 · I'm a high school student of grade 10 trying to work through some problems in a Data Structures and Algorithms book on Java. One of the questions is to print all permutations of a string.

May 1, 2013 · I have to print all the possible permutations of the given input string. Using the code below I get aaaa bbb ccc now in next iteration I want to print aaa aab aac. aba aca and so on.

Mar 23, 2013 · Effectively, what you do, is choose each string in turn and then find all permutations of the remaining strings, and prepend your chosen string. Choose A, get all permutations of {B,C,D} and append A. Choose B, get all permutations of {A,C,D} and append B. Choose C, get all permutations of {A,B,D} and append C. Choose D, get all permutations of ...

May 27, 2010 · For example I have this array: int a[] = new int[]{3,4,6,2,1}; I need list of all permutations such that if one is like this, {3,2,1,4,6}, others must not be the same.

Oct 1, 2012 · Before I start, I have to apologize for bringing up another case of permutations with duplicates. I have gone through most of the search results and can't really find what I am looking for.
