The 2018 World Cup will be hosted in Russia. 32 national teams will be divided into 8 groups. Each group consists of 4 teams. In group matches, each pair (unordered) of teams in the group will have a match. Top 2 teams with the highest score in each group will advance to eighth-finals. Winners of each eighth-final will advance to quarter-finals. Then, the winners of each quarter-final will advance to semi-finals. Eventually, the World Champion will be the winner of the World Final which is played between the two winners of the semi-finals.

Each match is labeled with a match ID sequenced from 1 to 63, with group matches followed by eighth-final matches followed by quarter-final matches followed by semi-finals matches and finally the final match.

Zhuojie is going to watch the 2018 World Cup. Since the World Champion of ACM-ICPC is very rich, he decides to spend 0.01% of his daily salary to buy tickets. However, there are only match IDs on the tickets and the prices are missing. Can you calculate how much Google pays Zhuojie every workday? Note that Zhuojie can buy multiple tickets for one match.

### Input ###

The input starts with one line containing exactly one integer *T*, the number of test cases.

Each test case contains 3 lines. The first line contains 5 integers, indicating the ticket price for group match, eighth-final match, quarter-final match, semi-final match and the final match. The second line contains one integer *N*, the number of tickets Zhuojie buys. The third line contains *N* integers, each indicating the match ID on the ticket.

*  1 ≤ *T* ≤ 100.
 *  1 ≤ *N* ≤ 105.

### Output ###

For each test case, output one line containing "Case \#x: y" where x is the test case number (starting from 1) and y is daily salary of Zhuojie.

## Example ##

### Input ###

1
    11 12 13 14 15
    2
    1 49

### Output ###

Case #1: 230000

### 题意描述： ###

已知世界杯比赛中32支队伍共要进行63场比赛，其中32进16为晋级赛，32支队伍分为8个小组，每个小组4支队伍；一组里的每两支队伍都要进行一场比赛；小组中的前两名晋级16强。而剩余16强进8强、8进4、半决赛和决赛都为淘汰赛。即随机分配两支队伍，胜者晋级，败者淘汰。每组样例有三行，第一行为五种比赛的门票价格，第二行为想要观看的比赛的总场次数，第三行为想要观看的比赛场次。求观看比赛需要花费多少钱。

### 解题思路： ###

有题意可知，1-48场为32进16的晋级赛，49-56场为16进8的淘汰赛，57-60场为8进4的淘汰赛，61-62场为4进2的半决赛，63场为决赛。将五种比赛的价格存储到数组中，输入观看场次，累加上该场次的对应价格。最后输出总价格，为防止数据溢出，可直接在输出数后加4个0，不需要乘上10000。

### 程序代码： ###

#include<stdio.h>
    int main()
    {
    	int t,m,i,j,n,a[10],sum;
    	scanf("%d",&t);
    	j=1;
    	while(t--)
    	{
    		for(i=1;i<=5;i++)
    			scanf("%d",&a[i]);
    		scanf("%d",&n);
    		sum=0;
    		for(i=1;i<=n;i++)
    		{
    			scanf("%d",&m);
    			if(m>=1&&m<=48)
    				sum+=a[1];
    			if(m>=49&&m<=56)
    				sum+=a[2];
    			if(m>=57&&m<=60)
    				sum+=a[3];
    			if(m>=61&&m<=62)
    				sum+=a[4];
    			if(m==63)
    				sum+=a[5];
    		}
    		printf("Case #%d: %d0000\n",j,sum);
    		j++;
    	}
    	return 0;
    }
