We use the center point of the rectangle to describe this rectangle. Then, for each enemy ship, we create an active range of the rectangular center, that is, the rectangular center will be able to overwrite the enemy ship within this range. the question we need becomes: Any region (which must be a rectangle) has the maximum value that can be covered by a rectangle.
