适用场景：需要求「下一个更大/更小」「上一个更大/更小」、或「右侧第一个满足某条件的元素」时，可优先考虑单调栈。与堆不同，单调栈不负责全局最值，只处理「相邻关系」类的一维序列问题。

Why we like itMost of the time, we see really stellar TV deals sell out as fast as they appeared. That's not the case for the 75-inch Hisense U7 Mini LED TV. We featured this "ultimate mid-premium" model from 2025 last week, but it's still down to just $899.99 at Amazon if you missed it.
