Quick Sort C Code Implement void QuickSort(int* pData,int left,int right){ int i = left, j = right; int middle = pData[(left+right)/2]; // midlle value int iTemp; do { while (pData[i] < middle && i < right) i++;
1. Select the Pivot Element There are different variations of quicksort where the pivot element is selected from different positions. Here, we will be selecting the rightmost element of the array as the pivot element. Select a pivot element 2. Rearrange the Array Now the elements of the array...

C语言实现几种常见排序算法 1.冒泡法 冒泡排序最好的时间复杂度为 O(n)。 冒泡排序总的平均时间复杂度为 O(n^2) 冒泡排序算法的原理如下: 1.比较相邻的元素。如果第一个比第二个大,就交换他们两个。 2.对每一对相邻元素做同样的工作,从开始第一对到结尾的最后一对。在这一点,最后的元素应该会是最...
[LintCode] Sort Integers II 整数排序之二 种排序算法,务必要掌握好。快排的优点是其平均时间复杂度为O(nlgn),这样在给大数据集排序的时候,其效率明显比一些O(n2)的算法要高很多。快排主要有三步: 1. 选定中枢点pivot value,中枢点可以选择中间那个点,也可以选末尾点,一般来说我们直接选取末尾点,如果选末尾...

使用QuickSort快速排序算法,排序一个链表。 下面是quickSort,因为quickSort算法的最坏情况是O(n*n), 所以如果做LeetCode上的Sort List这道题目,会遇上最坏情况超时的,不过这是个很好的算法,故此贴出来。 参考网站: http://www.geeksforgeeks.org/quicksort-on-singly-linked-list/ 也看了有些博客或...C++...
