³æç« ãPermutations IIãcpp é¢ç®: Given a collection of numbers that might contain duplicates, return all possible unique permutations. Based on Permutation, we can add a set to track if an element is duplicate and no need to swap. For example, [1,1,2] have the following unique permutations: [1,1,2], [1,2,1], and [2,1,1]. Java Solution 1. Permutations 47. Output of Primâs minimum spanning tree algorithm implemented in Python 3.6. For example: Given "25525511135", return ["255.255.11.135", "255.255.111.35"]. from itertools import permutations def permute_unqiue(nums, r): return list(set(permutations(nums, r))) This works by making a set() of the permutations. Example: Input: [1,1,2] Output: [ [1,1,2], [1,2,1], [2,1,1] ] For example, [1,1,2] have the following unique permutations: For numbers [1,2,2] the unique permutations are: [ [1,2,2], [2,1,2], [2,2,1] ] In the method which is called 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.
