Calculate Annual Bonus

You are given an employee's annual salary and a performance rating. Your task is to calculate the bonus based on the following formula:

\( Bonus = Salary \times r \)

where the ratio \( r \) is determined by the performance rating as follows:

• excellent: \( r = 0.20 \)
• good: \( r = 0.10 \)
• average: \( r = 0.05 \)
• Otherwise, \( Bonus = 0 \)

Read the salary and the rating from the standard input and output the calculated bonus to the standard output.

The input consists of two items provided via stdin: an integer representing the annual salary (guaranteed to be positive), and a string representing the performance rating. These will be separated by whitespace.
