To generate all the permutations of an array from index l to r, fix an element at index l and recur for the index l+1 to r. Backtrack and fix another element at index l and recur for index l+1 to r. Repeat the above steps to generate all the permutations. Based on Permutation, we can add a set to track if an element is duplicate and no need to swap. Let’s take a look at a slightly more complex problem. Problem Description.

For example, [1,1,2] have the following unique permutations: [1,1,2], [1,2,1], and [2,1,1]. This is not the case with fast_permutation. The algorithm is not as fast as the fast_permutation, but it is faster than the orginal one and than the pure python one available in test_itertools. One of the key advantage of python over other programming language is that it comes with huge set of libraries with it. 46. Java 1.22 KB .
