<sniff, sniff> ... smells like homework.

Which most monks are *happy* to help with ... on two conditions. a) you show a real effort, and b) you come clean and say it's homework rather than try to fool us or something. Thus far, you've failed both conditions, which explains why your node hasn't been approved yet (and I'm not going to do so, either).

Please show us what you have, and be honest about this being homework, and someone will be likely to help. Oh, and what you have should be more than what your teacher/professor/mentor gave you as a starting point. We'll know the difference.
