# Custom Set Create a custom set type. Sometimes it is necessary to define a custom data structure of some type, like a set. In this exercise you will define your own set. How it works internally doesn't matter, as long as it behaves like a set of unique elements. ## 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` and `--benchmem` flags: go test -v --bench . --benchmem 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. ## Further information For more detailed information about the Go track, including how to get help if you're having trouble, please visit the exercism.io [Go language page](http://exercism.io/languages/go/about). ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
