What sorting algorithm does list sort use?
Timsort is a hybrid stable sorting algorithm, derived from merge sort and insertion sort, designed to perform well on many kinds of real-world data. It was implemented by Tim Peters in 2002 for use in the Python programming language.
Which sorting algorithm is best for sorted list?
When the array is almost sorted, insertion sort can be preferred. When order of input is not known, merge sort is preferred as it has worst case time complexity of nlogn and it is stable as well. When the array is sorted, insertion and bubble sort gives complexity of n but quick sort gives complexity of n^2.
Which sort algorithm is fast to sorting list of elements?
The time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.
Which is sorting algorithm is used by STL’s list?
With that proviso, the short answer is that in most current standard libraries, std::sort is implemented as a intro-sort (introspective sort), which is basically a Quicksort that keeps track of its recursion depth, and will switch to a Heapsort (usually slower but guaranteed O(n log n) complexity) if the Quicksort is using too deep of recursion.
How to sort a list of a custom type?
Finally, if this makes sense, you can also equip your custom class with an operator<. That allows you to use the class freely in any ordered context, but be sure to understand the consequences of that. std::list ::sort has a one-argument form, with the first argument being the comparison function.
How to use the sort method in collections?
List .Sort Method. System. Collections. Generic. Sorts the elements or a portion of the elements in the List using either the specified or default IComparer implementation or a provided Comparison delegate to compare list elements.
How to sort by order in Microsoft Excel?
For example, if you want to re-sort the previous example by delivery date, under Sort by, choose delivery. From the Order drop-down, select Custom List. In the Custom Lists box, select the list that you want, and then click OK to sort the worksheet.
