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![Image 1][] yuan, while number with following features can be sold for  a![Image 1][] 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![Image 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![Image 1][], indicating number of test case.  
  
In the second line there is a positive integer  n![Image 1][], which means how many numbers Baby Ming has.(no two same phone number)  
  
In the third line there are  2![Image 1][] positive integers  a,b![Image 1][], which means two kinds of phone number can sell  a![Image 1][] yuan and  b![Image 1][] yuan.  
  
In the next  n![Image 1][] lines there are  n![Image 1][] cell phone numbers.（|phone number|==11, the first number can’t be 0)  
  
 1≤T≤30,b<1000,0<a,n≤100,000![Image 1][]

Output

How much Baby Nero can earn.

解题思路：

题目大意就是：

铭宝宝收集了很多手机号码，没错，他想卖手机号码赚钱。
    他觉得有如下性质的手机号码可以卖aaa元钱，其他的号码，只能卖bbb元钱。
    1.末5位数字相同（比如123-4567-7777）
    2.末5位是连续递增或者连续递减的，且相邻数位相差1的数（比如188-0002-3456）
    3.末8位是一个表示日期的数字，并且表示的日期在1980年1月1日至2016年12月31日内（比如188-1888-0809表示1888年8月9日）
    铭宝宝想知道卖掉所有的手机号码能赚多少钱。

输入T(T≤30)T(T \leq 30)T(T≤30)表示TTT组测试数据
    输入n(n≤100,000)n(n \leq 100,000)n(n≤100,000)表示铭宝宝有nnn张手机号码（没有相同的手机号码）
    输入222个正整数a,ba, ba,b, 表示两种类型的手机号码分别能卖aaa元和bbb元(b≤1000,a≤100,000)(b \leq 1000, a \leq 100,000)(b≤1000,a≤100,000)
    接下去nnn行，每行输入111个手机号码（|phonenumber|==11，首位非0）

所以简单模拟就行了，注意最后的结果会超int.
