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). WebDec 27, 2024 · It's safe to say that the complexity of the Union algorithm is equivalent to that of the Find algorithm. T (Union) = 2 * T (Find) + Constant_time Hence, T (Union) ~ …
