    题意倒是很容易理解,ac代码也是很短,但是理解确实不易,我自己归纳出来的结论,但是证明不了!
    说的好的也就这一个了:http://www.cnblogs.com/MiYu/archive/2010/08/18/1802685.html
    再贴个代码,记录下!
    #include <stdio.h>
    #include <string.h>
    
    int main()
    {
        int i,j,n,m;
        while(scanf("%d%d",&n,&m)!=EOF&&n||m)
        {
            if(n*m%2 != 0)printf("What a pity!
    ");
            else printf("Wonderful!
    ");
        }
        return 0; 
    }
