Hints

General

• Use the built-in (linked) list type.

1. Define a function to return an empty language list

• You need to define a named function with 0 arguments.

2. Define a function to add a language to the list

• You need to define a named function with 2 arguments. The first argument is a list of language string-literals. The second argument is a language string-literal.
• You can use list literal notation forms.

3. Define a function to remove a language from the list

• You need to define a named function with 1 argument. The first argument is a list of language string-literals.
• Elixir provides a function to return a list with the first item removed.

4. Define a function to return the first item in the list

• You need to define a named function with 1 argument. The first argument is a list of language string-literals.
• Elixir provides a function to get the first item from a list.

5. Define a function to return how many languages are in the list

• You need to define a named function with 1 argument. The first argument is a list of language string-literals.
• Elixir provides a function to count the length of a list.

6. Define a function to determine if the list is exciting

• You need to define a named function with 1 argument. The first argument is a list of language string-literals.
• Your function should return a boolean value indicating whether "Elixir" is a member of the list. Elixir provides a function to test list membership.
