On my first day in computer science class, the professor gave us an assignment that seemed deceptively simple: "Write a paper explaining how to make a peanut butter and jelly sandwich." At first glance, this task appeared trivial, almost laughable in its simplicity. After all, everyone knows how to make a peanut butter and jelly sandwich, right? You just spread the ingredients on two slices of bread and put them together, and you're done. But as I soon discovered, this exercise was not about making a sandwich; it was about teaching us the importance of detailed analysis.
