leetCode(33):Rectangle Area

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.

class Solution {
public:
    int computeArea(int A, int B, int C, int D, int E, int F, int G, int H) {
        int area1=(C-A)*(D-B);
    	int area2=(G-E)*(H-F);
    	if(B>=H || F>=D || E>=C || G<=A)
    	{//如果不相交
    		return area1+area2;
    	}
    	else
    	{
    		int length,width;
    		width=min(C,G)-max(A,E);//宽
    		length=min(D,H)-max(B,F);//长
    		return area1+area2-length*width;//面积之和减去重合部分面积		
    	}
    }
};
