SELECT ONE/MORE:

def permuterecursive (prefix, remaining): if remaining == 0): return (prefix] result = [] for n in remaining: copy = le for e in remaining) copy.remove(n) result += permuterecursive(prefix + [n], copy) return result def permute(n): return permuterecursive( [], range(1, n+1)) True statements on the python implementation: Select one or more: a. The python implementation works by growing the permutation of items similar with the depth first search algorithm b. Line "if remaining ==();" is used to add more items that have not been added to the sequence c. The complexity of the implementation is O(n logn) d. Line "copy.remove(n)" is to remove duplicate items in the set e. The python implementation works by growing the permutation of items similar with the breadth first search algorithm 0
