Here we use the next_permute() function, which rearranges the given string and returns the lexicographically next permutation. It just doesn’t seem as natural as iteration. For example, the permutation of ab will be ab and ba. Instead of printing Perm+word, only printing Perm is sufficient coz word is empty when we print the result. Hi Please find my approach to solve this problem:public static void main(String[] args) { printPermutationStrings("abcde"); } static void printPermutationStrings(String str){ printPermutationStrings("abcde", ""); } static void printPermutationStrings(String str, String prefix){ if(str == null || str.length() < 2){ return; } if(str.length() == 2){ System.out.println(prefix + str); System.out.println(prefix + new StringBuffer(str).reverse().toString()); } for(int i=0; i < str.length(); i++){ char c = str.charAt(i); String s2 = ""; for(int j = 0; j < str.length(); j++){ if(i != j){ s2 += str.charAt(j); } } printPermutationStrings(s2, prefix + c); } }. So base case is, when the length of our temporary string that needs to be printed is 3, print and return. Conclusion Permutations are the ways of arranging items in a given set such that each arrangement of the items is unique.

Let's start with an example, If we would take "xyz" as a string, the permutation of that string will be : xyz xzy yxz yzx zxy zyx (count : 3!=6) What will be the approach to solve, Step 1: If the length of the string is less than 2 then return the string. Combination is a collection of the elements where the order doesn’t matter; Permutation is an arrangement of a set where the order does matter. As a bonus, this also takes care of the case with duplicate characters in a string and prints only those that are unique. C has a function (next_permutation()), that modifies permutation (parameter) to next permutation (lexicographically greater), if such permutation exists is function return value is true, false otherwise. ( In this post we'll see both kind of solutions. Now we can insert first char in the available positions in the permutations. Example 2: Input: ABSG Output: ABGS ABSG AGBS AGSB ASBG ASGB BAGS BASG BGAS BGSA BSAG BSGA GABS GASB GBAS GBSA GSAB GSBA SABG … Software & Algorithms.
