## For bonus points

Did you get the tests passing and the code clean? If you want to, these
are some additional things you could try:

* Remove as much duplication as you possibly can.
* Optimize for readability, even if it means introducing duplication.
* If you've removed all the duplication, do you have a lot of
  conditionals? Try replacing the conditionals with polymorphism, if it
  applies in this language. How readable is it?

Then please share your thoughts in a comment on the submission. Did this
experiment make the code better? Worse? Did you learn anything from it?

## Running the tests

To run the tests run the command `go test` from within the exercise directory.

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.
