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…

Given n non-negative integers representing the histogram's bar height where the width of each bar is 1, find the area of largest rectangle in the histogram. Above is a histogram where width of each bar is 1, given height = [2,1,5,6,2,3]. The largest…

问题来源:Largest Rectangle in Histogram 问题描述:给定一个长度为n的直方图,我们可以在直方图高低不同的长方形之间画一个更大的长方形,求该长方形的最大面积.例如,给定下述直方图, 我们可以以高度5宽度2画一个更大的长方形,如下图,该长方形即是面积最大的长方形.该问题是难度比较大的问题,但是很出名,经常作为面试题出现.最近陈利人老师给出该问题的一个O(n)解法,非常巧妙,并从二维三维角度对问题进行了扩展.我们在陈老师的基础上,对该问题进行深入分析,给出多种方法,拓展大…
