【medium】78. Subsets

求集合不重複的子集：

下面python的寫法很好啊！

class Solution(object): def subsets(self, nums): """ :type nums: List[int] :rtype: List[List[int]] """ res = [[]] for num in nums : for temp in res[:] : x = temp[:] x.append(num) res.append(x) return res if __name__ == '__main__': x=Solution() res = x.subsets({1,2,3}) for r in res: print(r)
