浙江大学计算机科学与技术学院举办的趣味编程比赛“Let's C”采用独特的奖品分配规则，根据参赛者排名颁发神秘大奖、小黄人或巧克力。本文详细介绍了比赛规则，输入输出规范及示例，通过代码实现自动判断参赛者奖项。

1116 Come on! Let's C （20 分）

"Let's C" is a popular and fun programming contest hosted by the College of Computer Science and Technology, Zhejiang University. Since the idea of the contest is for fun, the award rules are funny as the following:

0、 The Champion will receive a "Mystery Award" (such as a BIG collection of students' research papers...).
1、 Those who ranked as a prime number will receive the best award -- the Minions (小黄人)!
2、 Everyone else will receive chocolates.

Given the final ranklist and a sequence of contestant ID's, you are supposed to tell the corresponding awards.

Input Specification:

Each input file contains one test case. For each case, the first line gives a positive integer N (≤104), the total number of contestants. Then N lines of the ranklist follow, each in order gives a contestant's ID (a 4-digit number). After the ranklist, there is a positive integer K followed by K query ID's.

Output Specification:

For each query, print in a line ID: award where the award is Mystery Award, or Minion, or Chocolate. If the ID is not in the ranklist, print Are you kidding? instead. If the ID has been checked before, print ID: Checked.

Sample Input:

Sample Output:

8888: Minion
0001: Chocolate
1111: Mystery Award
2222: Are you kidding?
8888: Checked
2222: Are you kidding?

具体判断：每行id的行号代表当前id的等级，从1开始，如果是1输出Mystery Award，如果是素数输出Minion，其他情况输出Chocolate，如果给的id不存在，输出Are you kidding? ,加入给的id已经判断过了，则输出Checked
