LeetCode 42. Trapping Rain Water - 单调栈（Monotonic Stack）系列题4
Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it can trap after raining. Example 1: Input: height = [0,1,0,2,1,0,1,3,2,1,2,1] Output: 6 Explanation: The above elevation map (black sec[Leetcode 42]雨天积水面积Trapping Rain Water

本文属于「征服LeetCode」系列文章之一，这一系列正式开始于2021/08/12。由于LeetCode上部分题目有锁，本系列将至少持续到刷完所有无锁题之日为止；由于LeetCode还在不断地创建新题，本系列的终止日期可能是永远。在这一系列刷题文章中，我不仅会讲解多种解题思路及其优化，还会用多种使用trap为shell的信号设置陷阱和陷阱运行原理以及如何复原默认信号处理
陷阱信号 当你的程序运行时，按下Control-C或者Control-, 一旦该信号到达程序就立刻终止运行。但是在很多的时候，你可能并不希望在信号到达的时候，程序就立刻停止运行。而是它能希望忽略这个信号而一直运行，或者在程序退出以前，做一些清除操作。trap命令允许你控制你的程序在收到【力扣42. 接雨水】单调栈+dp+双指针（Python3）

https://leetcode.com/problems/trapping-rain-water/ 这个问题我们采用的算法是全局遍历，找到最高点所在的index，然后对于左侧和右侧，分别计算蓄水量。对于左侧，蓄水量为左侧最大高度 – 当前高度，然后将蓄水量相加；右侧也是一样，从右向左遍历，蓄水量为右侧最大高度 – 当前高度。最后Leetcode 42. Trapping Rain Water (cpp)
题目 解法1：暴力 这题关键在于，每个位置能盛放多少水由这个位置左边的最大值和右边的最大值中的最小值决定的。到每个位置也只需要计算当前位置能盛放多少水即可。知道了这点，剩下的就是怎么优化罢了，原理都一样 class Solution { public: int trap(vector<int>& height) {【leetcode字节跳动题库】42. Trapping Rain Water
