编写一个函数，要求输入年月日时分秒， 输出该年月日时分秒的下一秒。 如输入2011年12月31日23时59分59秒， 则输出2012年1月1日0时0分0秒。 需要考虑闰年 和 2月的特殊情况 (Write a function that requires input date, hour, minute and second outputs of the date when the next second. If the input at 23:59:59 on December 31st, 2011, output at 0:00:00 on January 1, 2012. Leap year and February need to consider the special case)

说明：  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.
