Solution

Analysis

The coordination of the corner node of the intersection area is the the min and max of those coordinations.

Code

class Solution(object):    def computeArea(self, A, B, C, D, E, F, G, H):        """        :type A: int        :type B: int        :type C: int        :type D: int        :type E: int        :type F: int        :type G: int        :type H: int        :rtype: int        """        return (C-A)*(D-B) + (G-E)*(H-F) - max(0,min(C,G)-max(E,A))*max(0,min(D,H)-max(F,B))
