Leetcode: Subsets Given a set of distinct integers, S, return all possible subsets. Note: The solution set must not contain duplicate subsets. result.add(new ArrayList()); Subsets ( leetcode lintcode) Given a set of distinct integers, return all possible subsets. Thus, the given array can be divided into two subsets. The solution set must not contain duplicate subsets. Because given n elements, there will be O(n!) Previous posts were about Sliding Window, … } Given a collection of integers that might contain duplicates, nums, return all possible subsets (the power set). Explanation: The sum of the first and second elements equals the third element. The solution set must not contain duplicate subsets. Why I can’t use ” result.addAll(prev); ” as what you did in Subsets? Problem: Subsets.
