Task $1$: Financial application $-$ initial deposit amount.

Suppose you want to deposit a certain amount of money into a savings account with a fixed

annual interest rate. Write a program that prompts the user to enter the final account value, the

annual interest rate in percent, and the number of years, and then displays the initial deposit

amount. The initial deposit amount can be obtained using the following formula:

$=$

$(1+)\{\}$

Here is a sample run:

Enter final account value: $1000$

Enter annual interest rate in percent: $4\mathrm{.}25$

Enter number of years: $5$

Initial deposit value is $808\mathrm{.}8639197424636$
