Rectangle Area
问题：
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.

我的代码：
public class Solution { public int computeArea(int A, int B, int C, int D, int E, int F, int G, int H) { int oneArea = (C-A)*(D-B); int twoArea = (G-E)*(H-F); int left = Math.max(A, E); int right = Math.min(C, G); int down = Math.max(B, F); int top = Math.min(D, H); int intersect = 0; if(left < right && down < top) intersect = (right-left)*(top-down); return oneArea + twoArea - intersect; } }
