How to contribute

• upload input and solutions in the same PR. Name and clean up them properly
• when adding a new programming language, remember to update runtests.jl to "teach" it how to compile & run the <lang>

When testing locally, you can choose languages you want. For example, to avoid building C++ with bezel: to run - julia runtests.jl python cpp

> julia runtests.jl python cpp

• the input files should be named as <day>_<name>.txt, the content should be the input of the day without any dangling empty lines at the end
• the solutions files should be named exactly as corresponding input file, the content should be exactly one or two lines (depending on if you solved both parts)
• the src/<lang>/<day>_<optional name>.<ext> should matched the double-digit day number convention. The <lang> should match what appears in runtests.jl

Note for Julia

Each <day>_julia.jl script should use a main() and @__FILE__ pattern similar to:

function main(path)
    println("hello world")
    println("solution 2")
end

(abspath(PROGRAM_FILE) == @__FILE__) && main(ARGS[1])

this way we can put each script int a DayN module and compile only once per day.
