To find the area and perimeter of a rectangle in JavaScript, we will be using the basic formulas for the perimeter and area of a rectangle. The area of a rectangle is the multiplication of its length by its breadth, and the perimeter of a rectangle is the sum of the lengths of all ...
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. 解题思路: 几何题目。 代码如下: 1 2 3 4 5 6 7 8
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...
