Yen-Dollar Currency Converter

This problem requires you to implement a currency conversion tool. You are given two conversion rates: one for converting from Japanese Yen to US Dollar and another for converting from US Dollar to Japanese Yen. Then, you are provided with a number of queries. Each query is in the format C amount, where C is either Y (for converting Yen to Dollar) or D (for converting Dollar to Yen), and amount is a floating-point value.

Your task is to compute the conversion for each query. The result for each conversion must be rounded to 2 decimal places.

Formally, if the query is Y amount then the answer is given by:

\( result = amount \times \text{yen_to_dollar} \)

Similarly, if the query is D amount then the answer is given by:

\( result = amount \times \text{dollar_to_yen} \)

Print each converted result on a separate line.

inputFormat

The first line of input contains two space-separated floats: yen_to_dollar and dollar_to_yen.

The second line contains an integer Q representing the number of queries.

Each of the next Q lines contains a query in the format C amount, where C is either Y or D and amount is a float.

outputFormat

For each query, print the converted amount on a new line. The result must be rounded to 2 decimal places.
