Syntax ¶ sequence [start:stop [:step]] start Optional. Starting index of the slice. Defaults to 0. stop Optional. The last index of the slice or the number of items to get. Defaults to len (sequence). step Optional. Extended slice syntax. Step value of the slice. Defaults to 1. WebFeb 27, 2024 · If the output of the algorithm is the deep-copied string, the complexity is O (1), because you don't count the input nor output space. If the copy is used for internal purposes, then the complexity is at least O (N). But this is unrelated to the LeetCode question, which does not require a deep copy. brother justice mn
