UVa 220 （黑白棋）

这道题也是个模拟，没什么特别的想法，提交时一定要小心空格、\n一定不要多，否则会WA

这就是我冗长的代码：

//UVa 220
//Othello
#define LOCAL
#include <stdio.h> 
#include <string.h> //use memset strcmp

char chess[10][10], cnt;

        for(int j = 0; j < 8; j++)
            printf("%c", chess[i][j]);
        printf("\n");
    }
    if(T != 0)
    printf("\n");
}
