def quick_sort(l,low=0,high=0): #快速排序是递归实现的 #首先编写递归出口逻辑: #或者说递归继续深入的条件(包含了出口的意思) if(low<high): #首先对传入的区间片段做一个partition pivot_position=partion(l,low,high) quick_sort(l,low,pivot_position-1) quick_sort(l,pivot_position+1,high) 调用...
quick sort的主要思路是partition, 就是选一个element作为pivot,比如总是选最右边的element,然后将array走一遍,使得最左边的subarray都是小于或者等于pivot的值,接着都是大于pivot的值,最后将第一个大于pivot的element和pivot互换。然后返回这个pivot的index,接着再recursively 去sort pivot左边的array和pivot右边的array。

(a)What is Algorithm and Data Structure? Algorithm: Algorithms are basically methods or recipes for solving various problems. To write a program to solve some problems, we first need to know a suitable algorithm. 算法导论:非形式的说,算法就是任何良定义的计算过程,该过程取某个值或者值的集合作为...

The implementation of QuickSort is a bit different in the two cases. Arrays attempt to optimize the algorithm on the type of contained objects and do a lot more of exception handling and static checks that the DataView structure and internal design makes unnecessary....
