WebNov 24, 2024 · Please note that appending to lists is always O(1). So that shouldn’t impact the run time of the program. This is a more efficient way to concatenate strings rather than using a “+”. The time complexity of using join() for strings is O(n) where n is the length of the string to be concatenated. WebFeb 26, 2024 · We can't say what the time complexity is, because it depends on the implementation. There is no good reason why making a copy of a string with n characters should take O(n), and not O(1). Actually, implementors of standard libraries and languages will work hard to make sure the time is O(1).

WebSep 6, 2024 · Firstly, we need to relocate log (n) times, and every relocation is doubled by 2. So we have a proportional series whose ratio is 2, and the length is log (n). The sum of a proportional series is a (1-r^n)/ (1-r). So the total time of relocation is (1-n)/ (1-2)=n. The … WebOct 27, 2024 · Python list.pop(k) has a time complexity of O(k). ... which provides append and popleft functions to push an element in the end and pop the oldest element from the front, respectively.
