Create a program that uses a function named fv$()$ to calculate and output the future values $($future$\_$value$)$ given a principal amount $($p$),$ rate of interest $($r$),$ and the number of years $($years$)$ as its parameters. The formula for the future value is:

future$\_$value $=$ p $*((1+(0\mathrm{.}01*$r$))**$ years $)$

In other words, the function fv$()$ has three parameters $$ p$,$ r$,$ and years.

Additional requirements:

The principal amount $($p$)$ in the function definition has a default value of $1000($that is$,$ the argument for this parameter is optional$).$

The interest rate $($r$)$ in the function definition has a default value of $2\mathrm{.}5($another optional argument$).$

$**$Note that in a function definition, parameters with default values must appear AFTER parameters without default values.

At the beginning of the program, first use the input$()$ function to prompt users for the time period in years.

Use while loop to validate user inputs. If the time period a user inputted is less than $1,$ print out $$You must enter a value greater than or equal to $1.$ Then, prompt the user to enter the time period again. The program execution leaves the loop only when a user entered a value $>=1.$

When calling the function, only provide one argument: which is the time period $($year$)$ the user inputted:

fv$($year$)$

$**$In other words, use the default principal value $($p$)$ and interest rate $($r$)($see items A and B above$)$ for calculating the future value.

F$.$ Round the future value to two decimal places.$$

For example: If you type in a wrong value, you will see a warning message until you enter a value that is greater than or equal to $1.$

Please enter the time period in years: $0$

You must enter a value greater than or equal to $1.$

Please enter the time period in years: $-5$

You must enter a value greater than or equal to $1.$

Please enter the time period in years: $6$

Future value after $6$ years is $1159\mathrm{.}69$
