Algorithms & Logic The efficiency of your business logic directly impacts battery life and responsiveness. Complexity Analysis - Big O Awareness : Understand the cost of your operations. Avoid O(n²) or higher on the main thread for datasets larger than a few hundred items. - Data Structure Selection : - : Fast key-based lookups. - : Fast unique item management. - : Fast indexing and sequential access. - : Preserves insertion order while providing fast lookups. Logic Patterns - Debouncing : Delay execution until a user stops interacting (e.g., search-as-you-type). - Throttling : Limit executio…
