Instructions

The classical introductory exercise. Just say "Hello, World!".

"Hello, World!" is the traditional first program for beginning programming in a new language or environment.

The objectives are simple:

  • Modify the provided code so that it produces the string "Hello, World!".
  • Run the test suite and make sure that it succeeds.
  • Submit your solution and check it at the website.

If everything goes well, you will be ready to fetch your first real exercise.

Functions and testing

The starting code you're provided with,

(provide hello)

(define (hello)
  "Goodbye, Mars!")

defines a function named hello and makes it available to run. The test runner takes this function and runs it, comparing the value it returns to the value it expects. Use this starting function definition as the basis for your solution.
