Problem Description Recently kiki has nothing to do. While she is bored, an idea appears in his mind, she just playes the checkerboard game.The size of the chesserboard is n*m.First of all, a coin is placed in the top right corner(1,m). Each time one people can move the coin into the left, the underneath or the left-underneath blank space.The person who can’t make a move will lose the game. kiki plays it with ZZ.The game always starts with kiki. If both play perfectly, who will win the game?  

Input Input contains multiple test cases. Each line contains two integer n, m (0<n,m<=2000). The input is terminated when n=0 and m=0.

Output If kiki wins the game printf “Wonderful!”, else “What a pity!”.  

Sample Input 5 3 5 4 6 6 0 0  

Sample Output What a pity! Wonderful! Wonderful!

这题很简单。。。如果直接去PN分析，程序交上去会MLE。。。
只有先PN分析，然后找出规律：发现n和m都是奇数的话是P点，就是必败。。
具体分析不说了。很简单  

#include<stdio.h>
#include<string.h>
#include<iostream>
using namespace std;

int main()
{
    //init();
    int n,m;
    while(scanf("%d%d",&n,&m))
    {
        if(n==0&&m==0)break;
        if(n%2==1&&m%2==1)printf("What a pity!\n");
        else printf("Wonderful!\n");
    }
    return 0;
}
