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.
Rectangle Area
Assume that the total area is never beyond the maximum possible value of int.


Calculates the total area covered by the two rectangles.


The calculation method is the area of rectangle 1 + the area of rectangle 2-the area shared by the two rectangles.

Code Implementation

Algorithm Implementation class

Import java. util. *; public class Solution {public int computeArea (int A, int B, int C, int D, int E, int F, int G, int H) {long area = (long) (C-A) * (D-B) + (long) (G-E) * (H-F); // Math. min (C, G) indicates the smallest edge of the right side. // Math. max (A, E) indicates the largest edge on the left. // The subtraction below the edge will produce the more interface the array is, and the data range should be extended long width = Math. max (long) Math. min (C, G)-(long) Math. max (A, E), 0); // Math. min (D, H) indicates the smallest edge of the top edge. // Math. max (B, F) indicates the maximum side of the bottom edge. long height = Math. max (long) Math. min (D, H)-(long) Math. max (B, F), 0); return (int) (area-width * height );}}
