"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 (≤10^4), 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:
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?
题目大意: 给出n个学生的ID,他们的位置就是他们的排名。其中第一名会获得"Mystery Award",排名为素数的会获得“Minion”,其余排名都会获得“Chocolate”。之后k次查询,如果对应ID的学生出现过,且之前没有查询过,输出他对应的奖励;若之前查询过,输出Checked;若没有出现过,输出Are you kidding?
分析:用一个哈希表记录学生的名次,以及是否被查询过。之后每次查询对应输出即可。
