说明：  Description Michael喜欢滑雪百这并不奇怪， 因为滑雪的确很刺激。可是为了获得速度，滑的区域必须向下倾斜，而且当你滑到坡底，你不得不再次走上坡或者等待升降机来载你。Michael想知道载一个区域中最长底滑坡。区域由一个二维数组给出。数组的每个数字代表点的高度。elements in that rectangle. In this problem the sub-rectangle with the largest sum is referred to as the maximal sub-rectangle. ()

有2*n个盒子排成一行，其中有两个相邻的空盒，有n-1个盒子有符号 A ，有n-1个盒子有符号 B 。例如，n=5，并有初始配置如下： A B B A . . A B A B (2* n box row, wherein there are two adjacent empty box, n-1 of a box with the symbol ' A' , the symbol ' B' n-1 th box. For example, n = 5, and the initial configuration is as follows: ABBA .. ABAB)

说明：  以3月5日为例，应该先把前两个月的加起来，然后再加上5天即本年的第几天，特殊 　　　　　　 情况，闰年且输入月份大于3时需考虑多加一天。(To March 5, for example, should the first two months of the combined first and then add the 5th day of the first few days of this year, special circumstances, a leap year and enter the 3 months to consider more than one day.)

钟面上的时针和分针之间的夹角总是在 0 ～180之间 ( 包括 0 和180 ) 。举例来说，在十二点的时候两针之间的夹角为 0 ，而在六点的时候夹角为180 ，在三点的时候为90 。本题要解决的是计算 12:00 到 11:59 之间任意一个时间的夹角。(The angle between the hour and minute hands of the clock face is always between 0 to 180 (including 0 and 180). For example, twelve o' clock, when the angle between the two pin 0, in the six o' clock when the angle is 180, three points for 90. This question must be resolved are the angle of the calculation of 12:00 to 11:59 any one time.)
