Actually showing us what you have tried is probably the single most important thing that you could do to allow us to help you. It:

• possibly shows us what you are trying to do
• lets us see where you are coming from (how you are thinking)
• allows us to gage your current ability
• lets us see where you might have the wrong end of the stick
• shows us that you have made some effort
• allows us to help you resolve deeper stylistic issues
• gives you a chance to reappraise your code

So, regardless of how poor and irrelevant you think your code may be, please show us your code and, where appropriate, some sample input data, the output generated and the output expected.
