［抄题］: Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. [暴力解法]: 时间分析: 空间分析: ［思维问题］: 灌水的多少基本上由左右边界中较矮的一块木板开始,由相邻是否有较高的木板决定.第一次学灌水,算了 ［一句话思路］: ［输入量］:空:…

Given an m x n matrix of positive integers representing the height of each unit cell in a 2D elevation map, compute the volume of water it is able to trap after raining. Note: Both m and n are less than 110. The height of each unit cell is greater th…

题目描述 给定 n 个非负整数表示每个宽度为 1 的柱子的高度图,计算按此排列的柱子,下雨之后能接多少雨水. 上面是由数组 [0,1,0,2,1,0,1,3,2,1,2,1] 表示的高度图,在这种情况下,可以接 6 个单位的雨水(蓝色部分表示雨水). 感谢 Marcos 贡献此图. 示例: 输入: [0,1,0,2,1,0,1,3,2,1,2,1] 输出: 6 解题思路 基本思想是从数组首位置找到第一个大于其紧邻后面的数,将它作为第一个雨槽的左挡板,然后向后遍历找到第一个不小于它的的数作为右挡板…

题目:Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. For example,  Given [0,1,0,2,1,0,1,3,2,1,2,1], return 6. 例如给出上图中的黑色部分(数组表示),让你求出蓝色部分. 这也是个神题...当…

Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. For example, Given [0,1,0,2,1,0,1,3,2,1,2,1], return 6. The above elevation map is represented by a…

Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. The above elevation map is represented by array [0,1,0,2,1,0,1,3,2,1,2,1]. In this case, 6 units of…
