说明：  快速排序由C. A. R. Hoare在1962年提出。它的基本思想是:通过一趟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部分的所有数据都要小，然后再按此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 sorting was proposed by C. A. R. Hoare in 1962. The basic idea is: through a sort to two part sorting data into independent, a part of all of the data are all data than another to be a small part, and then according to the method of the two part of the data were quick sort, the ordering process can be performed recursively, in order to achieve the data into an orderly sequence.)
