Maximal Rectangle Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing all ones and return its area.     使用dpHeight[]数组来记录到第i行为止,第j个位置垂直连续包含多少个1(包括matrxi[i][j]).如: 1 0 1 1 0 1 1 0 1 0 0 1 1 1 1 有如下结果: 第1行: dpHeight[…

Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing all ones and return its area. 找到01矩形中最大的全1子矩阵. 我自己的思路: 我先用一个跟输入相同大小的矩阵numInCol 存储从当前位置开始向下有多少连续的1. 如 其numInCol 是 然后用一个变量tmpans来记录以某个位置开始,其右下矩形的最大全1矩阵的大小. 方法是如果当前位…

Find the total area covered by two rectilinear rectangles in a 2D plane. Each rectangle is defined by its bottom left corner and top right corner as shown in the figure. Assume that the total area is never beyond the maximum possible value of int. So…
