快速排序（Quicksort）是对冒泡排序的一种改进。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 Sort (Quicksort) is an improvement on the bubble sort. By CAR Hoare in 1962. The basic idea is: sort through the trip will be to sort the data is divided into two separate parts, the part of all of the data than the other part of the data to be small, then this method were both part of the data fast sort the entire sorting process can recursively, in order to reach the entire data into an ordered sequence.
