使用 JavaScript 的砖排序可视化

这基本上是冒泡排序的一种变体。该算法分为两个阶段——奇数阶段和偶数阶段。在奇数阶段，我们对奇数索引元素执行冒泡排序，在偶数阶段，我们对偶数索引元素执行冒泡排序。

GUI（图形用户界面）比程序有助于更好地理解。在本文中，我们将使用 JavaScript 可视化 Brick Sort。

先决条件：

• 砖排序。
• JavaScript 承诺。
• 基本的 HTML、CSS 和 JavaScript。
• JavaScript 异步/等待函数。

方法：

• 首先，我们将使用Math.random()函数生成一个随机数组。
• 不同的颜色用于指示哪些元素未排序（天蓝色）、比较（红色）和排序（浅绿色）。
• 按“Ctrl+R”键可以生成新数组。
• Button Brick使用选择排序算法对元素进行排序。
• 最后，对元素进行排序。

下面是上述方法的实现。
