3.2D Uses of Algorithms

What Algorithms Are For

Most software is built from a small set of everyday operations repeated over and over: putting data in order, finding an item, and picking out items that match a rule.
These jobs turn up everywhere: a music app or a bank both sorts, searches, and filters over the same data in different combinations.
Bigger systems are simple operations chained together: a recommendation feed scores items, sorts by score, and keeps only the top few.

Sorting

A sorting algorithm arranges items into an order (smallest to largest, newest to oldest, alphabetical). Sorted data is easier to scan and far faster to search.
Many sorting algorithms exist. Simple ones (bubble, selection, insertion sort) are easy but slow on large lists; cleverer methods sort huge datasets quickly. All reach the same result, differing only in work required.
Sorting is one of the most common operations in computing: leaderboards, search results, price comparisons, and calendars are all sorted before you see them, and the order shapes what you notice first.
Speed differences are huge at scale: studying algorithms is really the study of efficiency, reaching the same correct result with far less time and computing power.
