quick sort的主要思路是partition, 就是选一个element作为pivot,比如总是选最右边的element,然后将array走一遍,使得最左边的subarray都是小于或者等于pivot的值,接着都是大于pivot的值,最后将第一个大于pivot的element和pivot互换。然后返回这个pivot的index,接着再recursively 去sort pivot左边的array和pivot右边的array。

006.交换排序—快速排序(Quick Sort) 基本思想: 1)选择一个基准元素,通常选择第一个元素或者最后一个元素, 2)通过一趟排序讲待排序的记录分割成独立的两部分,其中一部分记录的元素值均比基准元素值小。另一部分记录的 元素值比基准值大。 3)此时基准元素在其排好序后的正确位置 4)然后分别对这两部分记录用...

Quicksort (also called partition sort and pivot sort) is arguably the most used sorting algorithm. It is the one commonly implemented internally in language runtimes. In this lesson we cover the quick sort algorithm, why is it calledquickand how to implement it using TypeScript / JavaScript. ...

or Insertion sort would perform better than Quicksort in the setup where only a few elements are out of order.Because these algorithms are adaptive, they can use the benefits of collections being presorted.However, on random sets of data, these algorithms may drive the entire system to a ...
