WebThe python page on time-complexity shows that slicing lists has a time-complexity of O (k), where "k" is the length of the slice. That's for lists, not strings, but the complexity can't be O (1) for strings since the slicing must handle more characters as the size is increased. At a guess, the complexity of slicing strings would also be O (k). WebJul 22, 2008 · == the time complexity of string indexing? Is it constant? Yes. == the time complexity of string slicing? Is it O(K) with K the slice's length? I suspect so, since the …
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).
