how do people solve the 3 Google Code Jam problems in 25 minutes?
manzyuk: I am curious, what languages did those of you who participated use for your solutions?  I have seen Ruby and Haskell mentioned.  I downloaded a few solutions of different participants at random, and they all were in C++.  I used Common Lisp (and my own small library of utility functions and macros), and it was a very satisfying experience.
