Pattern Recognition

Most programming problems follow common patterns. Once you recognize a pattern, you can apply a known solution approach. This is why experienced programmers solve problems faster; they've seen similar patterns before. The Accumulator Pattern This pattern builds up a result by processing items one at a time. You start with an initial value and update it in a loop. These three patterns cover the vast majority of beginner problems. Recognizing which one applies is often the hardest part, so here is a quick reference to help you decide. The Search Pattern This pattern looks for something in a collection, returning early when found. The Filter Pattern This pattern creates a new collection containing only items that match a condition. The accumulator, search, and filter patterns cover the vast m
