把一个8位二进制数的各位用ASCII码表示之（亦即为“0”的位用30H表示，为“1”的位用31H表示）。该数存放在内部RAM中byte单元中。变换后得到的8个ASCII码存放在外部RAM以buf始的存储单元中去。(To an 8-bit binary numbers that you use the ASCII code (which is " 0" bit with the 30H, said, " 1" bit said with 31H). The number stored in the internal RAM of byte unit. Transform ASCII code 8 by the external RAM to be stored in buf to the beginning of the storage unit.)

Background Given a set of rectangles {R1, R2, …, Rn}, compute the area of their common intersection. i.e., Area(R1∩R2∩…∩Rn) The edges of the rectangles R1, R2, …, Rn, are either vertical or horizontal lines. For example, the intersection of 4 rectangles, R1, R2, R3, and R4, in the following figure is the shaded rectangle. Input The input contains (N + 1) lines. The first line specifies the number of rectangles N, where 1 < N < 1000. Since the sides of the rectangles are parallel to the x-axis and y-axis, each rectangle is bounded by the lines x = x1, x = x2, y = y1 and y = y2 and each subsequent line of the input file thus specifies one rectangle in the following format: x1 x2 y1 y2 such that 0 <= x1 < x2 <= 10000 and 0 <= y1 < y2 <= 10000, and x1, x2, y1 and y2 are integers. Output The output file contains the area of the intersection of all the rectangles.
