Finally, you should write appropriate file header documentation for the program (in previous parts).

You will need to modify your work as follows:

• Add a parameter to the function which replaces the input variable from Part A
• This parameter will contain / accept a list of values which meets the input requirements from the previous parts
• You should assume that no invalid values are passed to this parameter and thus do not need to write additional validation for the parameter
• Your program should process the values provided in the list of values via the parameter, instead of using inputs from the user

Finally, write some test code that will execute only if the file is run directly (i.e. test code won't run when imported as a module), to demonstrate that the function does not crash and works correctly when provided values via its parameter.
