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... Rectangle)这一题的思路与上一题相同。主要是第一步。 首先我们先建立一个大小和Matrix相同的大小的二维数组map 通过向下累加的方式,更新map,然后在对每一行的
85--最大矩形(Maximal Rectangle) 这一题的思路与上一题相同。主要是第一步。 首先我们先建立一个大小和Matrix相同的大小的二维数组map intY=matrix.length;intX=matrix[0].length;int[][]map=newint[Y][X];for(inty=0;y<Y;y++) {for(intx=0;x<X;x++) {if(matrix[y][x]=='1') { /*假如...
Largest Rectangle in histogram LargestRectangleinhistogramquestion: 首先我们想到的简单的方法自然是对于任意一个bar,向左向右遍历 直到高度小于该bar,然后计算该区域的矩形面积。但是这样的算法复杂度比较高 不符合题目要求 下面我们介绍下另外一种算法: 从左从右遍历所有的bar,将其push到stack中 如果当前bar高度小于...
这转化为LeetCode《84.Largest Rectangle in Histogram》的问题。 解法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 public int maximalRectangle(char[][] matrix) { if (matrix.length==0||matrix[0].length == 0) return 0; int maxArea = 0; int[] height = new int[matrix[0].length]...
Maximal RectangleGiven a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing all ones and return its area.思路: 一行一行的记录下当前高度, 用上题的思路计算一下,即可。时间: O(n2)1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 ...
Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing all ones and return its area. 动态规划 + 栈 复杂度 时间O(NM) 空间 O(M) 思路 这题的解法基于上题。要求最大的矩形,实际上可以将矩阵的每一行,转化为上一题的直方图,而直方图的每个竖条的数字,就是该行...

Largest Interior Rectangle implementation in C# for Unity. REQUIREMENTS Unity.Mathematics is required for int2 and float2x2 (2D integer vectors and float 2x2 matrices, respectively). The simplest way to get this package is to open the "Package Manager" window in Unity, click the plus icon, ...
the frequencies of characters in texts. Note that the order of the rectangles, i.e., their heights, is important. Calculate the area of the largest rectangle in a histogram that is aligned at the common base line, too. The figure on the right shows the largest aligned rectangle for the ...
