@Illuminatus : Yes TA's are supposed to help, provided we have some. I just said I m new to perl so I dont know how to get started with these things. Thank you for replying back

@kennethK : thankyou for replying back I have edited my question and I hope this makes sense now. If you start telling me how to do things I will write my code on my own. I dont want any one to write a code for me.

@MidLifeXis: Yes this is a part of homework, I wanted a basic idea to do this. I am not expecting anyone to write a code for me. That is plagiarism. I dont have computer brains to help me figure out stuff that is why I came here to ask for help. Thanks for your valuable time
