择使用数组储存数据。*x,*y分别装入观察站的地理坐标，temp装入的是温度信息，*tpx,*tpy分别用作对x,y进行快速排序（tpx[2]=8表示排在第2位的是x[8],rank[8]=2表示x[8]排在第2位）升序，rankx[i]即为最终x[i]的排名。

为了方便计算一个范围内的温度值，定义了一个long long 型的数组sum。算出比点p小的点(不包括点p本身)的所有温度值之和sum，之后范围的四点sum相加减,再对少数点做处理即可得到范围内的温度之和。sum[i][j]表示的是rankx=i,ranky=j左下方的温度之和，相当于一个hashtable（映射关系）-Optional use arrays to store data.* X,* y respectively, into the geographical coordinates of the Observatory, temp temperature information is loaded,* tpx,* tpy respectively used for x, y quick sort (tpx [2] = 8 means that in the first two rows of the is x [8], rank [8] = 2 means that x [8] ranked No. 2) ascending, rankx [i] shall be final and x [i] in the rankings. In order to facilitate the calculation of the temperature within a range that defines a long long type array sum. Point p is smaller than the calculated points (not including the point p itself) of all temperature values ​ ​ and the sum, sum the four points of the range after the addition and subtraction, then do not handle a small number of points can be obtained and a temperature within the range. sum [i] [j] represents the rankx = i, ranky = j the temperature of the lower left, the equivalent of a hashtable (mappings)
