Java快速排序(Quick Sort) 快速排序(Quick Sort)是基于二分思想,对冒泡排序的一种改进。主要思想是确立一个基数,将小于基数的数字放到基数的左边,大于基数的数字放到基数的右边,然后再对这两部分数字进一步排序,从而实现对数组的排序。 其优点是效率高,时间复杂度平均为O(nlogn),顾名思义,快速排序是最快的排序...

Java代码实现快速排序(QuickSort) 核心思想 如果要排序数组中下标从p到r之间的一组数据,我们选择p到r之间的任意一个数据为pivot(分区点)。 我们遍历p到r之间的数据,将小于pivot的放到左边,将大于pivot的放到右边,将pivot放到中间。经过这一步骤之后,数组p到r之间的数据就被分成了三个部分,前面p到q-1之间都是小...

快速排序法——quicksort in java 用for遍历数组用while把当前值与前一个值比一下,如果满足条件,交换当前两个数据位置,直到条件不满足或者数组到0的位置。...核心: while条件ai的值。 if条件j– == 0,这个是数组坐标向下减,也就是往回走。...每次for循环一次,数组向前走一个,然后把这个位置的值取出来和前...
