It allows developers to predict how an algorithm will perform under heavy loads, ensuring systems remain responsive as data scales.
Time complexity measures the execution time of an algorithm, while space complexity measures the amount of working memory (RAM) it requires.
In theory, yes as input size grows to infinity. However, for very small inputs, an O(n) algorithm might execute faster than a complex O(1) algorithm due to constant factors.
