这是我们老师留的作业，恐怖吧！我想请问各位哥哥姐姐们，输入数据的和是怎么弄出来的呀？
The Problem
Mileage program of ACM (Airline of Charming Merlion) is really nice for the travelers flying frequently. Once you complete a flight with ACM, you can earn ACMPerk miles in your ACM Mileage Bank depended on mileage you actual fly. In addition, you can use the ACMPerk mileage in your Mileage Bank to exchange free flight ticket of ACM in future.
The following table helps you calculate how many ACMPerk miles you can earn when you fly on ACM.
When you fly ACM Class Code You'll earn
First Class F Actual mileage + 100% mileage Bonus
Business Class B Actual mileage + 50% mileage Bonus
Economy Class
1-500 miles
500+ miles
Y
500 miles
Actual mileage
It's shown that your ACMPerk mileage consists of two parts. One is your actual flight mileage (the minimum ACMPerk mileage for Economy Class for one flight is 500 miles), the other is the mileage bonus (its accuracy is up to 1 mile) when you fly in Business Class and First Class. For example, you can earn 1329 ACMPerk miles, 1994 ACMPerk miles and 2658 ACMPerk miles for Y, B or F class respectively for the fly from Beijing to Tokyo (the actual mileage between Beijing and Tokyo is 1329 miles). When you fly from Shanghai to Wuhan, you can earn ACMPerk 500 miles for economy class and ACMPerk 650 miles for business class (the actual mileage between Shanghai and Wuhan is 433 miles).
Your task is to help ACM build a program for automatic calculation of ACMPerk mileage.
Input
The input file contains several data cases. Each case has many flight records, each per line. The flight record is in the following format:
OriginalCity DistanceCity ActualMiles ClassCode
Each case ends with a line of one zero.
A line of one # presents the end of the input file.
It is guaranteed that the length of each city name does not exceed 1000 characters; and that the total length of each line in the input data does not exceed 4000 characters.
Output
Output the summary of ACMPerk mileages for each test case, one per line.
