    终于过了 题意理解错了,以为是任何一个3*3都要检查,再看发现只用检查9个

    对于水题就多做一点工作 这么麻烦的题,少写几行是个技术活 我想用集合直接判断是否相等应该比较简单,结果整50行。。。另外

    1.用read不用考虑换行问题,回车符直接省略掉 不过有的题好像必须readln

    2.不少人开布尔数组,不太好写,数据这么小,还是集合好

    3.有人用1~9的和是多少,积是多少判断,不论能否AC,这种算法有反例存在 还有人用上了方差(有创意。。。)仍有反例,但考试的时候可以拼一下RP,如果需要的话(哈希就这么来的)

    4.位运算怎么写? 谁教我一下?

    "没有读完一个数独的数而又已经能判断其为‘WRONG’时,直接跳到第2个数独,可能产生第2个和第9个测试数据错误"

    ---|-感谢zhengshuyuan牛的指点! 40行AC

    3*3的格用的 z[(i+2) div 3,(j+2) div 3,a] 貌似会慢...不过还是0ms

    用一个数组表示每行每列数的个数的情况,再用循环判断是否每一位上的数都为1,如不为1,退出循环,输出Wrong;如为1则清零准备下一次计数。

    九宫图用if判断==45即OK!

    (交了6次+,总结的经验)

    int main()

    {

    int n,a[10][10],x,i,j,s[10]={0},check[20]={0};

    scanf("%d",&n);
