This is are my very own solutions to some puzzlenode problems. The code is thought as solve-and-be-happy. Don't expect great-quality/refactored code here (it's not that bad either =D).
PuzzleNode is a site for coders who enjoy to work on challenging problems, and is inspired by similar efforts such as Project Euler and the Internet Problem Solving Contest. It also serves as an entrance exam of sorts for folks looking to join Mendicant University.
