Translator: Andrea McDonough Reviewer: Jessica Ruby What's an algorithm? In computer science, an algorithm is a set of instructions for solving some problem, step-by-step. Typically, algorithms are executed by computers, but we humans have algorithms as well. For instance, how would you go about counting the number of people in a room? Well, if you're like me, you probably point at each person, one at a time, and count up from 0: 1, 2, 3, 4 and so forth. Well, that's an algorithm. In fact, let's try to express it a bit more formally in pseudocode, English-like syntax that resembles a programming language. Let n equal 0. For each person in room, set n = n + 1. How to interpret this pseudocode? Well, line 1 declares, so to speak, a...
