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.
计算图形面积;
两个矩形面积减去重复的面积即可。
public class Solution { public int computeArea(int A, int B, int C, int D, int E, int F, int G, int H) { int area = (C - A) * (D - B) + (G - E) * (H - F); if (B > H || F > D || A > G || C < E) return area; int x1 = Math.max(A, E); int y1 = Math.max(B, F); int x2 = Math.min(C, G); int y2 = Math.min(D, H); int result = (x2 - x1) * (y2 - y1); if (result > 0){ return area - result; } else { return area + result; } } }
本文介绍了一种计算二维平面上两个矩形覆盖总面积的方法。通过分别计算两个矩形的面积并减去它们重叠部分的面积来得出最终结果。提供了一个具体的Java实现示例。
