Java [Leetcode 223]Rectangle Area 题目描述: 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 in...
@文心快码BaiduComate编写java程序,具体要求为: (1)定义一个计算面积的接口area,在接口中有计算面积的方法double getarea( )方法,再定义四个类分别是:正方形squre类、矩形rectangle类、梯形trapezoid类和圆circle类,这些类均需要实现area接口,并重写接口中的为getarea( )方法,该方法可以计算正方形、矩形、梯形和圆的...

Rectangle Area Assume that the total area is never beyond the maximum possible value of int. 数学法 复杂度 时间O(N) 空间 O(1) 思路 基本的数学题,考察的是我们能否全面的考虑到所有可能。如果两个矩形没有重叠部分,则直接计算两个矩形面积之和就行了。如果两个矩形有重叠部分,则要将重叠部分减去。如...
