题意: 给你两个空瓶子,只有三种操作 一.把一个瓶子灌满 二.把一个瓶子清空 三.把一个瓶子里面的水灌到另一个瓶子里面去(倒满之后要是还存在水那就依然在那个瓶子里面,或者被灌的瓶子有可能没满) 思路:BFS,打印路径时需技巧. //G++ 840K 0MS #include <iostream> #include <cstdio> #include <cstring> #include <cstdlib> #include <stack> #in…

//yy:昨天看着这题突然有点懵,不知道怎么记录路径,然后交给房教了,,,然后默默去写另一个bfs,想清楚思路后花了半小时写了120+行的代码然后出现奇葩的CE,看完FAQ改了之后又WA了.然后第一次用对拍去找特殊数据折腾到十二点半终于AC,最后只想感叹没有仔细读题,没办法啊看着英语略烦躁,不扯了,那个题题解不想写了,回到这题...今天中午还是花了四十分钟写了这题(好慢啊orz),感觉,啊为什么别人可以一下子就写出来,我却想不到怎么写呢!!! poj 3414 Pots  [BFS] 题意:两个…
