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 r…

问题描述: 84:直方图最大面积. 85:0,1矩阵最大全1子矩阵面积. 问题分析: 对于84,如果高度递增的话,那么OK没有问题,不断添加到栈里,最后一起算面积(当然,面积等于高度h * disPos,这里的高度取决于两个h的较小者,那么如果有序的话,只需要计算每一个最小值h,在用到当前位置与最小值h所在位置的差值,也就是柱子数目,就OK了).如果新h[i]的高度比之前的高度小的话,那么就可以认为之前所有比h[i]高的柱子都需要计算一下面积,然后对于破坏递增规则的h[i]会继续加入栈中.为甚会…
