Can you solve this real interview question? Subsets - 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: In
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], [] ] 链接:https://leetco...
Returnthe number of square-free non-empty subsets of the arraynums. Since the answer may be too large, return itmodulo109+ 7. Anon-emptysubsetofnumsis an array that can be obtained by deleting some (possibly none but not all) elements fromnums. Two subsets are different if and only if ...
