Find function in set time complexity

WebMar 12, 2024 · In general, if the time complexity of an algorithm is O (f (X)) where X is a characteristic of the input (such as list size), then if that characteristic is bounded by a constant C, the time complexity will be O (f (C)) = O (1). This is especially useful with certain algorithms that have time complexities that look like e.g. O (N ^ K).
