A stable sorting algorithm ensures that items that are equal to each other aren't reordered during the sorting process. For instance, suppose we're sorting a list of computer science majors by their grade point average. [('Mia', 3.9), ('Andrey', 3.2), ('Yvette', 3.9), ('Theo',...

Starting with ES10, the specification explicitly states that the Array.prototype.sort() method sorting algorithm must be stable (i.e. elements that compare equal must remain in their original order): // ES10+ const ratings = [ { name: 'foo', rating: 4 }, { name: 'bar', rating: ...
In order to grasp the functionality of stable_sort, it is important to understand what a stable sorting algorithm is. A stable sort preserves the original order of equal elements in a list, ensuring their relativepositions are unchanged after the sort. This is especially useful when sorting data...
要编写自定义比较函数来使用 stable_sort 函数进行稳定排序,我们需要定义一个函数,该函数接受两个参数并返回一个布尔值,用于指示哪个元素应排在前面。 以下是一个示例代码,演示如何编写一个自定义比较函数来对字符串长度进行稳定排序: #include <iostream> #include <algorithm> #include <vector> #include <string>...

Glidesort is a novel stable sorting algorithm that combines the best-case behavior of Timsort-style merge sorts for pre-sorted data with the best-case behavior of pattern-defeating quicksort for data with many duplicates. It is a comparison-based sort supporting arbitrary comparison operators, and...

Here are two applications: keap-based PriorityQueue as a replacement of java.util.PriorityQueue and Keapsort sorting algorithm. Both might be useful in two cases: stability is a must; comparing elements is rather heavyweight operation (e.g., it requires a database access). PriorityQueue PriorityQu...
