2. Another classic (twisted almost beyond recognition in case your answer to 1 is "nothing)": How would you do it with paper and scissors?

And welcome to PM. You'll really find a lot of help bere, but there is a third classic:

3. This is not a code-a-matic. There's no slot for your nickle/tuppence/Euro. But you will get back much more than you put in, when you show us your effort(s).

Update: Closed paren. Duh!
