Problem Description

Baby Ming collected lots of cell phone numbers, and he wants to sell them for money.

He thinks normal number can be sold for b yuan, while number with following features can be sold for a yuan.

1.The last five numbers are the same. (such as 123-4567-7777)

2.The last five numbers are successive increasing or decreasing, and the diffidence between two adjacent digits is 1. (such as 188-0002-3456)

3.The last eight numbers are a date number, the date of which is between Jar 1st, 1980 and Dec 31th, 2016. (such as 188-1888-0809,means August ninth,1888)

Baby Ming wants to know how much he can earn if he sells all the numbers.

 

Input

In the first line contains a single positive integer T, indicating number of test case.

In the second line there is a positive integer n, which means how many numbers Baby Ming has.(no two same phone number)

In the third line there are 2 positive integers a,b, which means two kinds of phone number can sell a yuan and b yuan.

In the next n lines there are n cell phone numbers.（|phone number|==11, the first number can’t be 0)

1≤T≤30,b<1000,0<a,n≤100,000

 

Output

How much Baby Nero can earn.

　　今天又仔细看了这道题，发现昨天少考虑一种情况，题目有三个要求1、后五位数字一样   2、后五位数字连续（可以递增也可以递减  忘记考虑递减的情况了）3、后八位可以组成一个日期，日期范围是1980年01月01号到2016年12月31号

接下来就主要处理每个月份对应时间以及闰年即可
