I know bisect search takes O(logn), but due to the insertion to the list, it really takes O(n). Where as the linked list implementation should also be O(n). Inserting new values in the sorted linked list should also be O(n). But why is the time comparison much … simon the fiddler

"WebNov 10, 2024 · 2 Answers. Both operations are O (1) amortized time-complexity. Appending elements to a list has a lower coefficient because it does not need to hash the element first, nor does it need to check/handle hash collisions. In the case of adding x into a set, Python needs to compute hash (x) first, because keeping the hash of all elements is … " - Bisect time complexity
