Quicksort is a popular sorting algorithm and is often used, right alongside Merge Sort. It's a good example of an efficient sorting algorithm, with an average complexity of O(nlogn)O(nlogn). Part of its popularity also derives from the ease of implementation. We will use simple integers ...

The basic idea of Quicksort algorithm can be described as these steps: 1. Select an element as a pivot element. 2. Data elements are grouped into two sections: one with elements that are in lower order than the pivot element, one with element that are in higher order than the pivot ele...
递归的最底层 quick sort:只有3个元素,中间的元素是分界值,把比它小的那个元素搬到左边,比它大的元素搬到右边,排序完成。 分区函数的思想: 抽出第一个元素,然后从列表最右端的元素开始,寻找比第一个元素更小的元素,搬到左边(=第一个元素的不移动); 从左边第一个元素开始(包括了第一个元素),寻找比第一个元...
