题目链接

题意：给定n堆石子，每次能在一堆取1到多个。取到最后一个赢，问谁赢

思路：就裸的的Nim游戏，利用定理求解

代码：

#include <stdio.h>
#include <string.h>

int n, num;

int main() {
	while (~scanf("%d", &n) && n) {
		int sum = 0;
  		for (int i = 0; i < n; i++){
			scanf("%d", &num);
			sum ^= num;
		}
		printf("%s
", sum == 0?
"No":"Yes");
 	}
	return 0;
}
