If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Write your code in the body of the sumOfAMultiple function in your multiples.js file so that the tests pass. The function will return the sum of all the multiples of 3 or 5 below n.

There are 4 tests in multiples-spec.js, once your first two tests pass, uncomment the last two and fill in the correct result.
