暴力做法是对每个位置向右扫描找第一个更大值，O(n²)。可抽象为：元素像一排人，身高为数值。当前人「下一个更大」= 他右侧第一个没被挡住的人（比当前矮的都被挡住）。单调栈用 O(n) 维护「右侧候选更大值」：倒序遍历，弹掉 ≤ 当前的，栈顶即答案，再入栈当前值。

，这一点在51吃瓜中也有详细论述
Work toward Gateway, a small space station that would orbit the moon and serve as a staging point for future missions, is not going away, officials said. But they made clear the agency’s priority is getting Artemis flights off the ground more often before building out that lunar outpost.
We have no way to skip over points that are obviously too far away. What if we could organize the space itself so that when we search, we can immediately rule out entire regions?
