Thanks for the reply! Do you feel like you have a sort of "intuition" for which things might work, and you experiment starting from that, or what is your general thought process like? Or maybe you start by drawing things out on pa

I really enjoyed this article, as someone who didn't finish highschool and is a professional programmer. The Wikipedia entry on Huffman Coding is impenetrable to me, this article was easy to follow.
