## 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?
|
|
|
|
To run the tests simply run the command `go test` in the exercise directory.
|
|
|
|
If the test suite contains benchmarks, you can run these with the `-bench`
|
|
flag:
|
|
|
|
go test -bench .
|
|
|
|
For more detailed info about the Go track see the [help
|
|
page](http://exercism.io/languages/go).
