There is a long standing debate amongst developers on which Self Balancing Binary Search Tree is better: AVL Trees or Red Black Trees. It's one of those age old debates the inspires religious like fervor in those which choose a side.
In the past I've primarily used two sources as reference material while implementing AVL trees: the example in Mastering Algorithms with Perl from O'Reilly, and Robert Sedgewick's description of the implementation from his book Algorithms. Both of thes
Pattern132 is an interesting problem I've seen floating around on various message boards. It is a constraint satisfaction problem that I've seen all manner of solutions for ranging from dynamic programming, to straight brute force iteration. When I fir

Early in my career, I had a lead developer on a project who during code review, much to my chagrin, kept making me re-write what was in my opinion “perfectly good, working code”. To my lead however
