题意:有n堆石子,每次可以将其中一堆分为数量不为0的3堆,或者从其中一堆中拿走若干个,最终拿完的那个人赢. 思路:直接暴力SG状态,然后找出其中的规律,异或一下每一堆的状态就可以了. #include<bits/stdc++.h> using namespace std; typedef long long ll; ;bool flag[maxn]; int sg[maxn]; int getSg(int x){ ) return sg[x]; memset(flag, , sizeof(fl…

题意:在nim游戏的规则上再增加了一条,即可以将任意一堆分为三堆都不为0的子堆也视为一次操作. 分析:打表找sg值的规律即可. 感想:又学会了一种新的方法,以后看到sg值找不出规律的,就打表即可~ 打表代码如下: #include <stdio.h> #include <algorithm> #include <string.h> #include <set> using namespace std; +]; int main() { sg[] = ; ;i…
