Questions regarding homework assignments are more than welcome, provided that they:
- Briefly explain the problem you are trying to solve; do not post your entire assignment verbatim.
- Explain what you have tried thus far, and where you are stuck.
- Don't ask for 'complete' solutions to the problem; we're not here to do your homework for you.
Questions should only be tagged as homework when either the asker has said it is so, or when it is blindingly obvious. For further guidelines, see the FAQ.
