Similarly, the Big-O notation for … WebApr 16, 2024 · Big O notation shows how an algorithm grows with respect to input size. It says nothing of which algorithm is faster because it doesn't account for constant set up time (which can dominate if you have small input sizes). So when you say which takes O (n) execution steps this almost doesn't mean anything.
