Python string slice time complexity
Did you know?
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). WebMar 29, 2024 · A Computer Science portal for geeks.
