Leetcode - Subsets Solution
Given an integer array nums
of unique elements, return all possible subsets (the power set).
The solution set must not contain duplicate subsets. Return the solution in any order.
Example 1:
Input: nums = [1,2,3]
Output: [[],[1],[2],[1,2],[3],[1,3],[2,3],[1,2,3]]
Example 2:
Input: nums = [0]
Output: [[],[0]]
Constraints:
1 <= nums.length <= 10
-10 <= nums[i] <= 10
- All the numbers of
nums
are unique.
Solution in Python
class Solution:
def subsets(self, nums: List[int]) -> List[List[int]]:
n = len(nums)
output = [[]]
for num in nums:
output += [curr + [num] for curr in output]
return output
