    要求子集,有很现成的方法。N个数。子集的个数是2^N。每一个元素都有在集合中和不在集合中两种状态,这些状态用[0,pow(2,N)]中每一个数来穷举,假设这个数中的第i位为1,说明当前集合中包括源数组中的第i个数。 至于有没有反复的元素,大部分有反复元素的问题,都能够借助一个vis集合,里面存放全部已经求得的集合或者其它形式的解。仅仅有少数题目会超时,哪些问题详细的说。 class Solu

    Subsets II -- LeetCode

    原题链接: http://oj.leetcode.com/problems/subsets-ii/ 这道题跟Subsets一样是经典的NP问题--求子集。比Subsets略微复杂一些的是这里的集合中可能出现反复元素,因此我们在求子集的时候要避免出现反复的子集。在Subsets中我们每次加进一个元素就会把原来的子集都加上这个元素,然后再增加到结果集中。可是这样反复的元素就会产生反复的

    [LeetCode]Subsets II生成组合序列

    class Solution {//生成全部【不反复】的组合。生成组合仅仅要採用递归,由序列从前往后遍历就可以。至于去重,依据分析相应的递归树可知。同一个父节点出来的两个分支不能一样(即不能与前一个元素一样,且前一个元素要与之在同层)。 public: int *b,n; vector<int>a; vector<vector<int>
