title: Source style for Google Code Jam
body: <p>I plan on doing the Code Jam competition next year. The problem is (something that I can't find anywhere) how do I set up my code to accept input and return an output?</p>
  
  <p>I'm just confused as to how I am supposed to handle everything, say for example that I have to add <strong>1</strong> to the input and make the result the output, how would I handle the input/output?</p>
  
  <p>I plan on using LUA. Thanks if you can. I think a code example would be best!</p>
