Title: Title PS matrix area is simple to understand, but not long long int types of inputs as well as the absolute value of a long time = = ~ fiddle

Title Description

The coordinates can determine a rectangle, a rectangular sorted output size of the area.

 

Entry

 Each row is given two coordinate points indicates a rectangle.
No more than 100 rectangles.

 

Export

Press the required output area.
