Write a method named presentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years as arguments. It should return the present value, which is the amount that you need to deposit today. Demonstrate the method in a program that lets the user experiment with different values for the formula’s terms
P = F/(1 + r)n
The terms in the formula are as follows:
• P is the present value, or the amount that you need to deposit today.
• F is the future value that you want in the account. (In this case, F is $10,000.)
• r is the annual interest rate.
• n is the number of years that you plan to let the money sit in the account.

Code a method named PresentValue that performs this calculation. The method
should accept the future value, annual interest rate, and number of years as arguments.
It should return the present value, which is the amount that you need to
deposit today. Demonstrate the method in an application that lets the user experiment
with different values for the formula's terms.
