Problem D 

Time Limit : 2000/1000ms (Java/Other)   Memory Limit : 32768/32768K (Java/Other)

Total Submission(s) : 21   Accepted Submission(s) : 3

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

zojozojoozoojoooozoojoooozoojozojooooozojozojoooo
 


Sample Output

AcceptedAcceptedAcceptedAcceptedAcceptedAcceptedWrong AnswerWrong Answer
