👉 In computer science, "fastness" refers to how quickly a program or algorithm performs compared to its theoretical maximum performance. It is often used in the context of optimizing algorithms for faster execution times by reducing unnecessary calculations and improving the efficiency of data access and processing. Fastness measures can be defined based on various criteria such as time complexity (O(n)), space complexity (O(1)), worst-case time complexity (O(|X|)), best-case time complexity (O(log n)), etc. These
