You can use Ellie to "test" the code, changing only the result function and adding your extra code

Extra documentation to use this as reference:

Data Modeling exercises

1 - Represent a package containing:

• barcode
• status ( can only be: Delivered, Failed, On Course)
• deliveryTime if the package was delivered (you can use String for this field)
• failedTime if the delivery fails (you can use String for this field)

2 - Create an address type that has 2 different shapes, it can be a coordinates address or a textual address:

1 - Coordinate address, with longitude and latitude

2 - Postal address, with address line, postal code, city and country

List.map exercises

1 - Create a function that receives a list of integers and returns a new list adding 1 in each item

• E.g. [1,2,3] -> [2,3,4]

2 - Given a list of strings, append "Hello " to each string

• E.g. ["jouderian", "miguel", "suraj"] -> ["Hello jouderian", "Hello miguel", "Hello suraj"]

3 - Given a package(barcode and status), returns the list of barcodes

  type alias Package =
    { barcode : String, status : String }
  
  packages : List Package
  packages =
    [ { barcode = "111111", status = "Delivered" }
    , { barcode = "2222222", status = "OnCourse" }
    , { barcode = "33333", status = "Delivered" }
    , { barcode = "44444", status = "FailedDelivery" }

Extra List exercises

This exercises are using different functions that we haven't discussed yet, but you can check the documentation here and try to do it

List docs

• Given a list of numbers, return all the numbers higher than 10
• Given a list of packages, return all the packages that are "Delivered"
