找规律

画一下图就知道了。

#include <stdio.h>

#include <string.h>

#include <iostream>

#include <algorithm>

using namespace std;



int main()

{

    int n,m;

    while(scanf("%d%d",&n,&m) == 2)

    {

        if(n==0 && m==0)break;

        if(n&1 && m&1)printf("What a pity!\n");

        else printf("Wonderful!\n");

    }

    return 0;

}
