Given a collection of integers that might contain duplicates, nums, return all possible subsets (the power set). Note: The solution set must not contain duplicate subsets. Input: [1,2,2] Output: [ [2], [1], [1,2,2], [2,2], [1,2], [] ] 题意: 是的[leetcode
Given a set of distinct integers, nums, return all possible subsets (the power set). Note: The solution set must not contain duplicate subsets. Example: Input: nums = [1,2,3] Output: [ [3], [1], [2], [1,2,3], [1,3], [2,3], [1,2], [] ] 题意: 给定一个含不同整数的集
