bfs+dfs 很复杂的搜索题. 因为数据很小,rock最多只有5个,coin最多只有10个,移动rock最多4^5=1024种状态: 思路: 每次先把当前状态能拿到的coin拿走,并将地图当前位置设为'.' (拿走coin的位置为空) 拿走coin后,在搜索一次,碰到rock判断是否能push动,能的话建立一个新地图,rock所在点设为'.' (空),rock移动到的点设为'X' (只能移动一次).就这样递归下去,因为只有5个rock,最对递归5层. 每次扫描完当前状态地图和以前拿到的最大值比…

前年的省赛题,难点在于这个石头的推移不太好处理 后来还是看了阳神当年的省赛总结,发现这个石头这里,因为就四五个子,就暴力dfs处理即可.先把石头当做普通障碍,进行一遍全图的dfs或者bfs,找到可以找的点,然后dfs每次探索新区域的新点即可,想通了这里很好做了 #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> using namespace std; ]…

A. Collecting Coins 题目链接:https://codeforces.com/contest/1294/problem/A 题意: 你有三个姐妹她们分别有 a , b , c枚硬币,你有n枚,你可以把硬币随意分给她们(必须分完),使她们的硬币数A = B = C 分析: 题目的条件有两点: ①A = B = C ②在满足①的前提下必须把硬币分完 我们首先要满足第一点.因为硬币个数有限,我们要尽可能用最少的硬币使 A = B = C,所以只要让a,b,c中小的两个等于最大的即可…
