leetcode--Subsets Given a set of distinct integers,S, return all possible subsets. Note: Elements in a subset must be in non-descending order. The solution set must not contain duplicate subsets. For example, IfS=[1,2,3], a solution is: [ [3], [1], [2], [1,2,3], [1,3],...
Given a set of distinct integers,nums, return all possible subsets. Note: Elements in a subset must be in non-descending order. The solution set must not contain duplicate subsets. For example, Ifnums=[1,2,3], a solution is: [ [3], [1], [2], [1,2,3], [1,3], [2,3], [...
LeetCode-Subsets Description: 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], [] ...
