in reply to Project Euler (a series of challenging mathematical/computer programming problems)

I've finished 9 so far, including a 15 point problem. A few hints for effective Perl usage:

  • bignum is your friend.
  • Not every problem is a math problem. (For example, I solved one problem with Date::Calc.)
  • Use iterative algorithms - recursion will blow your stack.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
