LeetCodeMathGeometryOpen on judge ↗

Given the coordinates of two rectilinear rectangles in a 2D plane, return the total area covered by the two rectangles. The first rectangle is defined by its bottom-left corner (ax1, ay1) and its top-right corner (ax2, ay2). The second rectangle is defined by its bottom-left corner (bx1, by1) and its top-right corner (bx2, by2). Example 1: Input: ax1 = -3, ay1 = 0, ax2 = 3, ay2 = 4, bx1 = 0,
