Hopefully, we will also provide a test environment so that you can upload a sample program and ensure that it builds and executes correctly on our platform. Thus, your best bet is to submit a statically linked executable and to include any files that you need. There are two forms of email submission 1. Submit a URL to your submission which we will then download, or 2. Submit an email with the submission as an attached file.
Details regarding the two options are below.
Remember that all submissions should be a single tarred and gzipped file with contents as specified above. Fill in each field as appropriate. Don't add anything else as it will confuse our parser. It's especially important to not add any leading white space to the lines. The subject of the email and the name of the submitted file do not matter.
