You can't figure.... to be blunt thats because it seems like you're not trying.

You can't ask where to start, when you get stuck, ask for help. If you don't know where to start, then go back to the basics.... If you ask the right kinds of questions, people will be glad to help you learn.

But besides the point it's an aptitude test and if you can't code, you'll probably fail. You can't pretend you can, we will know. Don't expect to be spoon fed the code the whole way there. Try it yourself
