Sum Of Multiples

Given a number, find the sum of all the multiples of particular numbers up to but not including that number.

If we list all the natural numbers up to but not including 20 that are multiples of either 3 or 5, we get 3, 5, 6 and 9, 10, 12, 15, and 18.

The sum of these multiples is 78.

Given a number, find the sum of the multiples of a given set of numbers, up to but not including that number.

Running the tests

If the test suite contains benchmarks, you can run these with the -bench flag:

go test -bench .

Keep in mind that each reviewer will run benchmarks on a different machine, with different specs, so the results from these benchmark tests may vary.
