84题和85五题 基本是一样的,先说84题 84--柱状图中最大的矩形( Largest Rectangle in Histogram) 思路很简单,通过循环,分别判断第 i 个柱子能够延展的长度len,最后把len*heights[i] 就是延展开的面积,最后做比对,得出最大. public int largestRectangleArea(int[] heights) { int ans=0; for(int i=0;i<heights.length;i++) { int len=1,lef…

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,…

在某篇博客见到的Largest Rectangle in Histogram的题目,感觉蛮好玩的,于是想呀想呀,怎么求解呢? 还是先把题目贴上来吧 题目写的很直观,就是找直方图的最大矩形面积,不知道是受之前的trie tree影响怎么的,感觉树这玩意还真有用,于是就思考呀,还真别说,真想出一种方式,好吧,其实是入了一个大坑,也无妨,记录下来,好歹也是思路历程..... 大概思路这样的: 每次寻找直方图的最小值,记录此时以该最小值,和以其为高度的矩形面积,再将直方图以该最小值为界限,将直方图分成若…
