If you’re in the majority of people, you’re likely confused as you open this book and begin your adventure with algorithms, because most texts never tell you what an algorithm is, much less why you’d want to use one. Hearing about algorithms is like being in school again with the teacher droning on; you’re falling asleep from lack of interest because algorithms don’t seem particularly useful to understand at the moment.

The first section of this chapter is dedicated to helping you understand precisely what the term algorithm means and why you benefit from knowing how to use algorithms. Far from being arcane, algorithms are actually used all over the place, and you have probably used or been helped by them for years without really knowing it. So, they’re stealth knowledge! In truth, algorithms are becoming the spine that supports and ...
