题目: poj 2352 Stars 数星星 题意:已知n个星星的坐标.每个星星都有一个等级,数值等于坐标系内纵坐标和横坐标皆不大于它的星星的个数.星星的坐标按照纵坐标从小到大的顺序给出,纵坐标相同时则按照横坐标从小到大输出. (0 <= x, y <= 32000) 要求输出等级0到n-1之间各等级的星星个数. 分析: 这道题不难想到n平方的算法,即从纵坐标最小的开始搜,每次找它前面横坐标的值比它小的点的个数,两个for循环搞定,但是会超时. 所以需要用一些数据结构去优化,主要是优化找 横坐…

STARS的全称是Space-Time Analysis of Regional Systems,直译过来就是区域系统时空分析软件.这是针对区域多时相数据的分析包,源代码公开.该软件将最近几年发展起来的时空分析技术引入到友好的用户界面中,设计目标是要成为一款探索性数据分析软件. 不得不说的是,探索性空间数据分析(ESDA)在国内才刚刚起步,而STARS面向的则是更为复杂的探索性时空数据分析(ESTDA).因而,多了解这样一个软件无异可以为国内GIS研究开辟一个新方向. 此软件为圣迭戈州立大学地理…
