A collection of various algorithms, data structures, and so forth for reference when studying for things like interviews.
My primary references are "Cracking the Coding Interview", "Algorithms" 4th Edition, and www.StackOverflow.com.
*Note 1: Most of these were written by hand and tested after the fact in preperation for interviews. I re-tested most of them as I added them here, but they should be taken "as-is". Please report any bugs or errors! :)
**Note 2: Many of these are not complete java classes. Some are just a single method. Others are partially complete classes. Some are complete, runnable classes w/ or w/out main()'s. Make sure you check what you're dealing with before just trying to run the code by itself!
