作为一位web开发者, 懂得怎样去规划一个页面的尺寸是很重要的. 现给定一个具体的矩形页面面积,你的任务是设计一个长度为 L 和宽度为 W 且满足以下要求的矩形的页面.要求: 1. 你设计的矩形页面必须等于给定的目标面积. 2. 宽度 W 不应大于长度 L,换言之,要求 L >= W . 3. 长度 L 和宽度 W 之间的差距应当尽可能小. 你需要按顺序输出你设计的页面的长度 L 和宽度 W. 示例: 输入: 4 输出: [2, 2] 解释: 目标面积是 4, 所有可能的构造方案有 [1,4],…

题目描述 给定 n 个非负整数,用来表示柱状图中各个柱子的高度.每个柱子彼此相邻,且宽度为 1 . 求在该柱状图中,能够勾勒出来的矩形的最大面积. 以上是柱状图的示例,其中每个柱子的宽度为 1,给定的高度为 [2,1,5,6,2,3]. 图中阴影部分为所能勾勒出的最大矩形面积,其面积为 10 个单位. 示例: 输入: [2,1,5,6,2,3] 输出: 10 解题思路 这道题跟LeetCode 11很相似,但是因为考虑柱子宽度,因此解题技巧不相同,此题考查单调栈的应用.我们首先在数组最后加入0,…

Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing all ones and return its area. 此题是之前那道的Largest Rectangle in Histogram 直方图中最大的矩形 的扩展,这道题的二维矩阵每一层向上都可以看做一个直方图,输入矩阵有多少行,就可以形成多少个直方图,对每个直方图都调用Largest Rectangle in Hist…

之前切了道求解最大正方形的题,题解猛戳 这里.这道题 Maximal Rectangle 题意与之类似,但是解法完全不一样. 先来看这道题 Largest Rectangle in Histogram,如果暴力求解,可以枚举每个点为最小值,向两边扩展,复杂度 O(n^2).我们可以维护一个栈,从而将复杂度降低到 O(n),这个栈的思维非常巧妙,参考了 discuss,我是完全想不出来(或者说忘记了).具体代码可以猛戳 这里. 2016-08-07 补:stack 数组维护的是一个单调递增的数组,…

A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates of its top-right corner. Two rectangles overlap if the area of their intersection is positive.  To b…
