题意:              给你起点,终点,图上有墙有路还有宝物,问你在规定时间内能否能到终点,如果能问最多能捡到多少宝物. 思路:           看完这个题目果断 BFS+三维的mark[][][] 第三维用二进制压缩的思想去解决,结果TLE了,我后来在网上看了看,发现有人用二进制压缩ac了,这更坚定了我的决心啊,不停的优化 超时 优化 超时 就这样我超时了 50多次,我tm恶心了,直接粘了个网上说和我想法一样的代码交上去了,结果 TLE 了, 我 fuck ,超时了早说啊... …

http://acm.hdu.edu.cn/showproblem.php?pid=1044 代码题,没什么好说的,先预处理出两点间距离,然后dfs搜一下找最大值 #include <iostream> #include <cstdio> #include <algorithm> #include <queue> using namespace std; const int INF=0xfffffff; int n,m,L,M,ans,sum; ][]; ]…

题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=2822 题目大意:X消耗0,.消耗1, 求起点到终点最短消耗 解题思路: 每层BFS的结点,优先级不同,应该先搜cost小的.直接退化为最短路问题. 优先队列优化. 卡输入姿势.如果O(n^2)逐个读的话会T掉.要用字符串读一行. #include "cstdio" #include "queue" #include "cstring" using…
