poj-2488 题意:一个人要走遍一个不大于8*8的国际棋盘,他只能走日字,要输出一条字典序最小的路径 题解: (1)题目上说的"The knight can start and end on any square of the board.",是个坑点,其实要走字典序最小只需从A1开始遍历就行,因为从任意一点开始,只要能遍历完整个地图,那么A1也可以: (2)要使字典序最小,那么遍历顺序一定要注意 int dr[8]={-1,1,-2,2,-2,2,-1,1};int dc[8]=…

题意: 给一个集合,有n个可能相同的元素,求出所有的子集(包括空集,但是不能重复). 思路: 看这个就差不多了.LEETCODE SUBSETS (DFS) class Solution { public: vector<vector<int>> subsets(vector<int>& nums) { sort(nums.begin(),nums.end()); DFS(,nums,tmp); ans.push_back(vector<int>()…
题意: 给一个集合,有n个互不相同的元素,求出所有的子集(包括空集,但是不能重复). 思路: DFS方法:由于集合中的元素是不可能出现相同的,所以不用解决相同的元素而导致重复统计. class Solution { public: vector<vector<int>> subsets(vector<int>& nums) { sort(nums.begin(),nums.end()); DFS(,nums,tmp); return ans; } void DF…
