不管是否使用技能,发现操作前后所有堆二进制中1的个数之和不变.那么对于一个堆其实可以等价转换为一个k个石子的堆(k为该数二进制的个数),然后就是个nim游戏. 1 #include<bits/stdc++.h> 2 using namespace std; 3 int t,n,ans,a[101]; 4 int main(){ 5 scanf("%d",&t); 6 for(int ii=1;ii<=t;ii++){ 7 scanf("%d"…

Stone Game II HDU - 4388 题目大意: 给出n堆物品,每堆物品都有若干件,现在A和B进行游戏,每人每轮操作一次,按照如下规则: 1. 任意选择一个堆,假设该堆有x个物品,从中选择k个,要保证0<k<x且0<(x^k)<k. 2. 再增加一个大小为x^k的堆(也就相当于将一个x个物品的堆变成一个k个物品的堆和一个x^k个物品的堆),另外有一个技能,可以将这个大小为x^k的堆变成(2*k)^x的堆,但是这个技能每个人只有一次机会可以使用. 现在问两人轮流操作,都采…

LINK 题意:n堆石子,Alice 和 Bob 轮流取石子,谁不能再取或被对方取完为败.但是对于alice拥有限制:b=0此堆正常无限制:b=1此堆Alice只能取奇数个石子:b=2只能取偶数个石子 思路:一看就知道是个NIM的变形题,现在想做这题的思路应当是讨论奇偶个石子且分别在奇数偶数限制下的胜负状况. 很容易能看出当有两堆以上的限制堆时(a=1 b=1不算限制)显然是Alice必败,这是最重要的条件,可以避免大量的推导. 再者讨论b=1的情况: 如果a为偶数,显然该堆可被Bob保证不被A…
