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.
Example:
Input: A = -3, B = 0, C = 3, D = 4, E = 0, F = -1, G = 9, H = 2
Output: 45
Note:
Assume that the total area is never beyond the maximum possible value of int.
代碼:
class Solution { public: int computeArea(int A, int B, int C, int D, int E, int F, int G, int H) { int sum = (C - A) * (D - B) + (H - F) * (G - E); if (E >= C || F >= D || B >= H || A >= G) return sum; return sum - ((min(G, C) - max(A, E)) * (min(D, H) - max(B, F))); } };
先算出來兩個面積的和 然後判斷有沒有重合 如果有減去重合如果沒有直接返回面積和
