Note: The solution set must not contain duplicate subsets. Leetcode Subsets II，本问题与Subsets 类似，只是需要处理重复子集问题，这个问题，我们可以使用每次从长度为m的子集构成长度为m+1的子集时，只对等值的元素添加一次，这样就可以保证没有重复现象，处理代码与Subsets类似，如下：#include #include #includeusing namespace std; Leetcode 888. getSubsets(S, .push_back(S[i]); For example,If S = [1,2,2], a solution is: 这道子集合之二是之前那道 Subsets 的延伸，这次输入数组允许有重复项，其他条件都不变，只需要在之前那道题解法的基础上稍加改动便可以做出来，我们先来看非递归解法，拿题目中的例子 [1 2 2] 来分析，根据之前 Subsets 里的分析可知，当处理到第一个2时，此时的子集合为 [], [1], [2], [1, 2]，而这时再处理第二个2时，如果在 [] 和 [1] 后直接加2会产生重复，所以只能在上一个循环生成的后两个子集合后面加2，发现了这一点，题目就可以做了，我们用 last 来记录上一个处理的数字，然后判定当前的数字和上面的是否相同，若不同，则循环还是从0到当前子集的个数，若相同，则新子集个数减去之前循环时子集的个数当做起点来循环，这样就不会产生重复了，代码如下：, 对于递归的解法，根据之前 Subsets 里的构建树的方法，在处理到第二个2时，由于前面已经处理了一次2，这次我们只在添加过2的 [2] 和 [1 2] 后面添加2，其他的都不添加，那么这样构成的二叉树如下图所示：, 代码只需在原有的基础上增加一句话，while (S[i] == S[i + 1]) ++i; 这句话的作用是跳过树中为X的叶节点，因为它们是重复的子集，应被抛弃。代码如下：, https://leetcode.com/problems/subsets-ii/, https://leetcode.com/problems/subsets-ii/discuss/30137/Simple-iterative-solution, https://leetcode.com/problems/subsets-ii/discuss/30168/C%2B%2B-solution-and-explanation.
