水题,转化Nim
代码如下:
1 #include<iostream> 2 #include<stdio.h> 3 #include<algorithm> 4 #include<iomanip> 5 #include<cmath> 6 #include<cstring> 7 #include<vector> 8 #define ll __int64 9 #define pi acos(-1.0) 10 #define MAX 50000 11 using namespace std; 12 int m,t,ans; 13 int main(){ 14 while(scanf("%d",&m)&&m){ 15 ans=0; 16 while(m--){ 17 scanf("%d",&t); 18 ans^=t; 19 } 20 puts(ans==0?"Grass Win!":"Rabbit Win!"); 21 } 22 return 0; 23 }
