Description:
"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 (≤), 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 isMystery Award
, orMinion
, orChocolate
. If the ID is not in the ranklist, printAre you kidding?
instead. If the ID has been checked before, printID: Checked
.
Sample Input:
6 1111 6666 8888 1234 5555 0001 6 8888 0001 1111 2222 8888 2222
Sample Output:
8888: Minion 0001: Chocolate 1111: Mystery Award 2222: Are you kidding? 8888: Checked 2222: Are you kidding?
Keys:
- 素数(Prime)
Attention:
- 对于较大规模的数据,采用打表的方法可以大大的优化时间,平时应该养成习惯已备不时之需;
