Permutation
from itertools import permutations from itertools import combinations p = permutations([1,2,4]) # or permutations([1, 2, 3], 2) for i in p: print(i) c = combinations([1,2,3],2) for j in c: print(j)
permutation
Input: nums = [1,2,3] Output: [[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,1,2],[3,2,1]]
