快速排序,快速排序是对冒泡排序的一种改进。它的基本思想是：通过一躺排序将要排序的数据分割成独立的两部分，其中一部分的所有数据都比另外一不部分的所有数据都要小，然后再按次方法对这两部分数据分别进行快速排序，整个排序过程可以递归进行，以此达到整个数据变成有序序列。-Quick Sort, Quick Sort Bubble Sort is an improvement. Its basic idea is: lying through one sorting to sort the data to be split into two independent parts, one part of all of the data than the other one is not part of the all the data should be small, and then meeting the two methods were part of the data quick sort, the entire sorting process can be recursive, and thus the entire data into an orderly sequence.

GPS定位数据压缩算法的设计与实现 文章作者：杨宏业 张 跃 为了解决嵌入式GPS车载系统存储空间小、GPS定位数据量大的矛盾，根据GPS定位数据的特 点，提出了专用于GPS定全数据压缩的改进型半字节压缩算法。-the design and implementation of GPS locaton data compression algrithm.author:yanghongye,zhangyao.solve the problem of gps car-carring system with little memory ,while heavy dataload.according gps data s characteristic ,put forward gps-oriented data compression,improved half byte compression algrithm.
