Each of these problems is in two halves:

a) Understanding the mathematics behind the question
b) Writing the code.

Which half are you halfing (oops sorry, *having*) trouble with? If
(a), this isn't a programming question at all - search the web for
information on the problem, as these are well-known challenges. If
(b), you'll need to post your code to get any sort of useful help - we
aren't mindreaders, though we do try to look that way sometimes!
