题意:与原来基本的尼姆博弈不同的是,可以将一堆石子分成两堆石子也算一步操作,其它的都是一样的. 分析:由于石子的堆数和每一堆石子的数量都很大,所以肯定不能用搜索去求sg函数,现在我们只能通过找规律的办法求得sg的规律. 通过打表找规律可以得到如下规律:if(x%4==0) sg[x]=x-1; if(x%4==1||x%4==2) sg[x]=x; if(x%4==3) sg[x] = x+1. 打表代码: #include<iostream> #include<cstdio> #…

http://acm.split.hdu.edu.cn/showproblem.php?pid=5724 题意: 现在有一个n*20的棋盘,上面有一些棋子,双方每次可以选择一个棋子把它移动到其右边第一个空位置处,谁不能移动了谁就输. 思路: 找规律好像找不着,那么就考虑SG函数了,因为一共只有20列,所以可以状态压缩处理,这样就可以方便的得到某个状态的后继状态. #include<iostream> #include<algorithm> #include<cstring&g…

题意:给定一个日期,然后 A 和 B 双方进行操作,谁先把日期变成2001年11月04日,将获胜,如果超过该日期,则输了,就两种操作. 第一种:变成下一天,比如现在是2001.11.3 变成 2001.11.4 第二种,变成下一个月的同一天,比如现在是2001.10.3 变成 2001.11.3,当然有可能是不成立的,比如2001.1.30 不能变成2001.2.30,因为2月没有30天. 析:因为题目中说了是从1990年到2001年,大约100年的时间,也就是400 * 100,完全可以存储下…
