Setting up the Judge on Windows

Windows 10 Anniversary Update

This is the recommended way to run the DMOJ on Windows, but requires the Windows Subsystem for Linux (WSL) that was added in the Windows 10 Anniversary Update. You will need to enable the subsystem before proceeding.

Open Bash by tying bash in command prompt, or running it directly.

We'll need a couple of packages to get started, after which we can begin setting up the judge.

init.yml specifies signatures for all methods, e.g.:

    int findSwapPairs(int, int[], int, int[])
    functions:
        findSwapPairs: (I[II[I[I[I[I)I

There are two types of functions: functions that the grader calls from C->Java, and functions that Java calls that are implemented in C. The latter is slightly easier to discuss.

We can autogenrate Java classes binding those methods statically, e.g.:
