2. Remove a language from a list
Modify the remove-language subroutine to remove the last language from a given list.
3. Fetch the first language from a list
Modify the first-language subroutine to return the first language from a given list.
4. Fetch the last language from a list
Modify the last-language subroutine to return the last language from a given list.
5. Fetch a slice of languages from a list
Modify the get-languages subroutine, which takes a list of languages and a list of numbers for wanted elements, to return a slice of the given list.
6. Check if a language exists in a list
