Leetcode: Permutations II
题目： Given a collection of numbers that might contain duplicates, return all possible unique permutations For example, [1,1,2] have the following unique permutations: [1,1,2], [1,2,1], and [2,1,1]. 这道题和前面Leetcode: Permutations类似，不过给定序列中有重复的序列。 采用Leetcode: Permutations思路二，不过我们在交换的过程中发现有相同元素出现的时候不进行交换就OK了。 C++参考代码： （可以对比Leetcode: Permutations思路二的代码，其实两者改动的地方就是啊判断要不要交换） class Solution { private: vector

题目 排列组合嘛。 用DFS 递归一下，输出就好了。又不会超时的 class Solution { public: vector<vector<int>> ans; vector<int> res; int vis[100005]; vector<vector<int>> permute(vector<int>& nums) { fun(nums,0); return ans; } void fun(vector<in

详见上一题：http://blog.csdn.net/qqxx6661/article/details/78154064 投机取巧：将数组排序，然后就可以和前面一个数对比，如果重复直接忽略掉。只需新增3行代码

题目 这一题多了一个条件就是，会有重复的数字， 在上一题的基础上加一个约束条件就可以了。 class Solution { public: vector<vector<int>> ans; vector<int> res; int vis[100005]; vector<vector<int>> permuteUnique(vector<int>& nums) { sort(nums.begin(),nums.end());
