overview

the image and tests support the following languages:

• Bash
• C++
• Go
• Python
• R

usage

1. build the image for testing with make build.
2. write solutions in files named <dd>/{a,b}/main.{sh,cpp,go,py,R}.
   1. starter files can be created using starter.go. usage is below.
   2. each program/script should output the answer (and only the answer) to stdout.
   3. each program/script should expect exactly one command line argument, which is the file containing the input data.
   4. these are available in the running container via a volume, so the image does not need to be rebuilt after writing a new solution.
3. test all solutions for a given day/part with make test path=<dd>/{a,b}/, e.g. make test path=05/a/.
4. once there is a correct solution for a given day/part, add it to answers.json in a format like the following:

{
  "ans01": {"a": "foo", "b": "bar"},
  "ans02": {"a": "123"}
}

notes

• test all solutions in the above languages for all days/parts with make test.
• clean up the repo, build the image, and test all solutions with make all.
• starter.go usage:

  -day uint
        day {1,...,25} (default 1)
  -lang string
        language {cpp,go,R,py,sh} (default "cpp")
  -part string
        part {a,b} (default "a")
