There can be many ways to do partition, following pseudo code adopts the method given in CLRS book. The logic is simple, we start from the leftmost element and keep track of index of smaller (or equal to) elements as i. While traversing, if we find a smaller element, we swap current...

The logic is simple, we start from the leftmost element and keep track of index of smaller (or equal to) elements as i. While traversing, if we find a smaller element, we swap current element with arr[i]. Otherwise we ignore current element. Pseudo code for partition() /* This functio...

This article explains how to implement three popular sorting algorithms—Bubble Sort, Merge Sort, and Quick Sort—in Java. It provides simple, step-by-step explanations for each algorithm, including how they work, their code implementations, and their ad
The pivot element is the one in the middle, 1. (You could also have picked 2, it doesn't matter.) Again, we create three subarrays around the pivot: 中间元素是中间的1(你也可以选择2,这没关系)。再次,我们围绕中间元素创建了三个子数组:...
快速排序 Thinking in QuickSort 快速排序 1.大致的介绍: 快速排序(QuickSort)是一种有效的排序算法。虽然算法在最坏的情况下运行时间为O(n^2),但由于平均运行时间为O(nlogn),并且在内存使用、程序实现复杂性上表现优秀,尤其是对快速排序算法进行随机化的可能,使得快速排序在一般情况下是最实用的排序方法之一。
