QuickSort is faster in practice, because its inner loop can be efficiently implemented on most architectures, and in most real-world data. QuickSort can be implemented in different ways by changing the choice of pivot, so that the worst case rarely occurs for a given type of data. However,...

图源:Geeks4geeks 快速排序的思想: 基于第一个元素,将比它小的元素移动到它的左边;比它大的元素,移动它的右边(partition 分区函数) 对左边区域使用快速排序; 对右边区域使用快速排序。 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...
Quick Sort是目前已知的最快的排序法,平均复杂度为O(NlogN),最坏的情况下将达O(N2);不过(极类似median-of-three QuickSort的一种排序算法)可将最坏情况推进到O(logN)。早期的STL sort算法都是采用Quick Sort,SGI STl以采用IntroSort。 Quick Sort算法可以叙述如下。假设S代表将被处理的序列: 1、如果S的元素...
