WebPython’s Timsort algorithm has O (n log n) worst-case time complexity and O (n) best-case time complexity if the list is already largely sorted. It also has excellent benchmark results —it outperforms many of the best sorting algorithms in the world on real-world input data. Worst-case performance Best-case performance Average performance WebMay 21, 2014 · Cpython uses TimSort (a hybrid of insertion sort an mergesort) which I believe has O (N) complexity if the input is already sorted -- It picks up the best case …
WebRemove all values from sorted list. Runtime complexity: O (n) discard (value) [source] ¶ Remove value from sorted list if it is a member. If value is not a member, do nothing. Runtime complexity: O (log (n)) – approximate. >>> sl = SortedList( [1, 2, 3, 4, 5]) >>> sl.discard(5) >>> sl.discard(0) >>> sl == [1, 2, 3, 4] True Parameters WebMar 21, 2024 · Best Case: The best time complexity for Insertion sort is O (n). Advantages It is simple and easy to implement. It performs well while dealing with a small number of data elements. It does not need more space for its implementation. Disadvantages It is not helpful to sort a huge number of data elements.
WebOct 5, 2024 · When you have a single loop within your algorithm, it is linear time complexity (O (n)).

WebSorting The Python list sort () has been using the Timsort algorithm since version 2.3. This algorithm has a runtime complexity of O (n.logn). The function has two optional attributes which can be used to specify a customized sort: The key attribute requires a callable function as its input. The function will specify the sorting criteria.
