// GENERATED /* INSTRUCTIONS * * Complete the exercises below. For each "EXERCISE" comment, add * code immediately below the comment. * * Please see README.md for instructions, including compilation and testing. * * GRADING * * 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. Altering it in your submission will * result in 0 points for this assignment. * * 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. * * SUBMISSION * * 1. Push your local repository to the repository created for you on Bitbucket before the deadline. * * 2. Late submissions will not be permitted because solutions will be discussed in class. * */ object dynamic { trait Internationalization { def greet (name : String) : String } // EXERCISE 1: complete the following function. // 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".
