<题目链接> 题目大意: 有两个容量的空杯子,能够对这两个空杯子进行三种操作: 分别是fill(a),装满a杯子: drop(a),倒空a杯子: pour(a,b),将a杯子中的水倒入b杯子中: 现在问你,是否能够通过这三种操作,使得这两个杯子中至少有一个杯子中含有c体积的水,如果不行,输出“impossible”,如果可以,输出操作的步数,以及每一步的具体操作. 解题分析: 此题与一道输出路径的很相像,只不过那道题是输出每一次操作对应的点的状态,而此题是要输出具体的操作.不难想到,我们依然可…

//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…

主要是学一下如何在广搜中记录路径:每找到一个点我就记录下这个点是由那个点得来的,这样我找到最后个点后,我就可以通过回溯得到我走过的路径,具体看代码吧~ #include<cstdio> #include<stdio.h> #include<cstdlib> #include<cmath> #include<iostream> #include<algorithm> #include<cstring> #include<…
