Problem Description
对给定的字符串(只包含'z','o','j'三种字符),判断他是否能AC。

是否AC的规则如下:
1. zoj能AC;
2. 若字符串形式为xzojx,则也能AC,其中x可以是N个'o' 或者为空;
3. 若azbjc 能AC,则azbojac也能AC,其中a,b,c为N个'o'或者为空;
 

 

Input
输入包含多组测试用例,每行有一个只包含'z','o','j'三种字符的字符串,字符串长度小于等于1000;
 

 

Output
对于给定的字符串,如果能AC则请输出字符串“Accepted”,否则请输出“Wrong Answer”。
 

 

Sample Input
zoj
ozojo
ozoojoo
oozoojoooo
zooj
ozojo
oooozojo
zojoooo
 

 

Sample Output
Accepted
Accepted

//坑点:
    <1>:串中一定有'Z', 'J';   'Z', 'J'中间一定有‘O’
    <2>:对于满足<1>的串,如a ‘Z’ b 'J' c 一定满足 a*b=c || a=c=0;
