1. 结果

红色为被选中的pt

1.1 结果图

1.2 动画图

1个pt排好序后就把该pt标红

2. 代码

2.1 快排代码

  private Integer selPt(List<Integer> list, int left, int right) {if (left >= right) {return left;}int ptVal = list.get(left);int l =left, r=right;while (l < r) {while (l < r && list.get(r) > ptVal) {r--;}while (l < r && list.get(l) <= ptVal) {l++;}if (l < r) {int t = list.get(l);list.set(l, list.get(r));list.set(r, t);}}list.set(left, list.get(l));list.set(l, ptVal);return l;}public void quickSort(List<Integer> list, int l, int r) {if (l >= r) {return;}int pt = selPt(list, l, r);quickSort(list, l, pt-1);quickSort(list, pt+1, r);}

2.2 绘图代码

参照 冒泡排序可视化

要想实现结果图中代码 需要稍加改造 选出来pt后指定该pt位置的颜色
