Please see below link for a solution that prints only distinct permutations even if there are duplicates in input.Print all distinct permutations of a given string with duplicates. To avoid duplicates, we need to enforce the constraint that no character will be selected twice to place in the prefix before calling the subproblems. The next post discusses a custom recursive implementation of how to achieve the same thing. A permutation, also called an “arrangement number” or “order,” is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with S itself. Then I will discuss a method to improve the performance in case if character repeats. 2. Test your Python skills with w3resource's quiz. String Permutations is a way to uniquely arrange all the letters of the string. In mathematics, the notion of permutation relates to the act of arranging all the members of a set into some sequence or order, or if the set is already ordered, rearranging (reordering) its elements, a process called permuting.
