And whether or not this is homework (label it that if it is and you will be less likely to be scorched), the basic ethos here is that we are happy to help folk learn, but decidedly unhappy about those who seek to have us earn their wages or their grades for them.
So, the classic Monastery question, "What have you tried?" is shorthand for "you will get better answers if you show us you have put some of your own effort into the project."
As to your multiple questions:
- "...hw hard is to programe... (sic)"
Not at all hard or maybe, "too hard" -- depending on what you have learned about perl (and, in this case, as marto suggests, TK).
- "...too difficult..."
See answer one if you are asking how hard it would be for you; see paragraph one if your question is how hard the wisest Monks would find this exercise.
- "...able..."
assuredly.
- "...have time..."
If that reflects a view that your time is more valuable than ours, probably not! On the other hand, even I am writing this in hopes that you will see your visits here as a chance to learn (not merely beg, borrow or steal, nor merely "cargo cult some code"). So then consider this a "warm welcome..." and you will do well to read the introductory material in the right sidebar and, especially, How do I post a question effectively?.
Update ungarble some of my writing. Replacement or new matter is bold; replaced content is striken (as am I upon reading this after coffee).
