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? ## Getting Started For installation and learning resources, refer to the [exercism help page](http://exercism.io/languages/ocaml). ## Installation To work on the exercises, you will need `Opam` and `Core`. Consult [opam](https://opam.ocaml.org) website for instructions on how to install `opam` for your OS. Once `opam` is installed open a terminal window and run the following command to install core: ```bash opam install core ``` To run the tests you will need `OUnit`. Install it using `opam`: ```bash opam install ounit ``` ## Running Tests A Makefile is provided with a default target to compile your solution and run the tests. At the command line, type: ```bash make ``` ## Interactive Shell `utop` is a command line program which allows you to run Ocaml code interactively. The easiest way to install it is via opam: ```bash opam install utop ``` Consult [utop](https://github.com/diml/utop/blob/master/README.md) for more detail. ## Feedback, Issues, Pull Requests The [exercism/ocaml](https://github.com/exercism/ocaml) repository on GitHub is the home for all of the Ocaml exercises. If you have feedback about an exercise, or want to help implementing a new one, head over there and create an issue. We'll do our best to help you! ## Source Learn to Program by Chris Pine [http://pine.fm/LearnToProgram/?Chapter=06](http://pine.fm/LearnToProgram/?Chapter=06) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
