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。
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...
dataStructure_交换排序(冒泡排序bubbleSort/快速排序QuickSort),由于引入了枢轴变量p,我们可以将被选为枢轴的元素(比如第一个元素L[0]备份到p)在非最坏情况下,可以借助标记位,可以提前判断出

Yet, in attempting to code it using a recent programming language of our design, we discovered that its structure is more clearly expressed as a concurrent program that manipulates a shared mutable store, without any locking or explicit synchronization. In this paper, we describe the essential ...
Recursion in data structure is a process where a function calls itself directly or indirectly to solve a problem, breaking it into smaller instances of itself.
