LightOJ 1247 Matrix Game

把每一行看成一堆，然后就是一道基础的Nim博弈了

#include <cstdio>int main(){    int T;    scanf("%d", &T);    for(int ca = 1; ca <= T; ca++)    {        int n, m;        scanf("%d%d", &n, &m);        int sg = 0;        for(int i = 0; i < n; i++)        {            int t, sum = 0;            for(int j = 0; j < m; j++)            {                scanf("%d", &t);                sum += t;            }            sg ^= sum;        }        printf("Case %d: %s\n", ca, sg != 0 ? "Alice" : "Bob");    }    return 0;}
