What are the most popular algorithms in programming?

Question

I want to learn the most important algorithms that every programmer should know.

Answer 1

well, how to store and retrieve data from a database is (almost) always a must.
Sort methods are the most newbie stuff one should learn.
Other stuff can vary in what the project is about, but you need to know how to create your algorithms to resolver your own problems. (or at least, how to use other algorithms to resolve your own problems :P)
