Problem Statement

Exchange rates:

  • 1 USD = 0.71 JOD
  • 1 USD = 0.92 EUR
  • 1 USD = 0.82 GBP

The conversion formula is:

Converted Amount = Amount in USD × Exchange Rate

The user will input:

  1. The amount in USD (a floating-point number)
  2. A number representing the target currency:
  • 1 for JOD
  • 2 for EUR
  • 3 for GBP

If the user selects an invalid option (not 1, 2, or 3), print INVALID OPTION.

Round the converted amount to two decimal places.

Input Format

The input consists of two lines:

  1. A floating-point number representing the amount in USD.
  2. An integer representing the target currency (1 for JOD, 2 for EUR, 3 for GBP).

Output Format

Print the converted amount with exactly two decimal places followed by the currency code (e.g., 71.00 JOD). If the option is invalid, print INVALID OPTION.
