And that's it. Although I've shown you a lot of code in this article, the main focus is really on why you want to rotate keys. How you do it is just an implementation detail.。关于这个话题，谷歌提供了深入分析
思路：倒序单调栈。弹出所有 ≤ 当前身高的元素（这些人都能被看到），count 为弹出数量；若栈非空，还能看到栈顶（第一个更高的人），故 +1。能看到的人数 = count + (栈非空 ? 1 : 0)。。超级工厂对此有专业解读
