博弈又快忘了，记住了又能怎样……

本题是在方格子中顺着左、下、左下的方向动，若长和宽有一个为偶数，那么kiki就可以顺着这个方向有路可走

#include <iostream>
#include<cstdio>
using namespace std;
int n,m;
int main()
{
    while(cin>>n>>m)
    {
        if(n==0&&m==0) break;
        if(n%2&&m%2)
        puts("What a pity!");
        else
        puts("Wonderful!");
    }
    return 0;
}
