So, we will make the permutations of 2, 3 and 4 by keeping 2 fixed. I would like any general feedback on the implementation of the recursive algorithm. In mathematics, arranging all the members of a set into some order or sequence and if the set is already ordered, rearranging (reordering) its elements is called permutation. Getting all the Permutations of String in Python Program: For permutations, we can use backtracking technique. Dictionary is an example of a group of words sorted in a lexicographical manner.
