Rectangle Area
[Leetcode]https://leetcode.com/problems/rectangle-area/
題意：
ind 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.
解題思路：
public class Solution {
public int computeArea(int A, int B, int C, int D, int E, int F, int G, int H) {
int sums = (C - A) * (D - B) + (G - E) * (H - F);
if (D < F || H < B) {
return sums;
}
if (C < E || G < A) {
return sums;
}
int right = Math.min(C, G);
int left = Math.max(A, E);
int top = Math.min(H, D);
int bottom = Math.max(F, B);
return sums - (right - left) * (top - bottom);
}
}
