78. Subsets
[Medium] “Given a set of distinct integers, nums, return all possible subsets (the power set), withotu duplicate subsets."
Note: old solution, should review (TODO:)
Python3:
class Solution:
def subsets(self, nums: List[int]) -> List[List[int]]:
res = [[]]
for num in nums:
size = len(res)
for i in range(size):
res.append(res[i] + [num])
return res
