/* INSTRUCTIONS * Complete the exercises below. For each "EXERCISE" comment, add

* code immediately below the comment.

* 1. Submissions MUST compile using SBT with UNCHANGED configuration and tests with no * compilation errors. Submissions with compilation errors will receive 0 points. * Note that refactoring the code will cause the tests to fail.

* 2. You MUST NOT edit the SBT configuration and tests.

* 3. You MUST NOT use while loops or (re)assignment to variables (you can use "val" declarations,

* but not "var" declarations). You must use recursion instead.

* 4. You may declare auxiliary functions if you like.

// It has two parameters:

// - i18n : (a reference to) an instance of a class that extends / implements the Internationalization trait (interface) defined above.

// - name : a String

// You should use the "greet" method of "i18n" to find a greeting for "name". Return the result.

// EXERCISE 2: complete the following function.

// It should return an instance of a class that extends / implements the Internationalization trait (interface) defined above.

// The "greet" method should return a String consisting of "Hello", a space, and the name given as an argument.

// You can either define classes inside the newEnglish method or directly inside the "dynamic" object.

// EXERCISE 3: complete the following function.

// It should return an instance of a class that extends / implements the Internationalization trait (interface) defined above.

// The "greet" method should return a String consisting of "Bonjour", a space, and the name given as an argument.

// You can either define classes inside the newFrench method or directly inside the "dynamic" object.
