quickSort(arr, 0, n - 1); printf("Sorted array: "); for (int i = 0; i < n; i++) { printf("%d ", arr[i]); } return 0; } 在这个实现中，我们首先定义了一个swap函数来交换两个元素的值。然后我们定义了一个partition函数，它选择一个基准元素，然后将数组分为两部分，一...
Stuck using quickSort to sort an ArrayList Hans Hovan Ranch Hand Posts: 40 posted 11 years ago I'm writing a program that is supposed to sort objects (people, companies, etc.) based on criteria like last name, then first name, then ID number, and so on. The objects being sorted ...

1. Declare an array of some fixed capacity, lets say 30. 2. From users, take a number N as input, which will indicate the number of elements in the array (N <= maximum capacity) 3. Iterating through for loops (from [0 to N) ), take integers as input from user and print them...
快速排序(quickSort)是由东尼·霍尔所发展的一种排序算法。 在平均状况下,排序 n 个项目要 Ο(nlogn) 次比较。在最坏状况下则需要 Ο(n2) 次比较,但这种状况并不常见。事实上,快速排序通常明显比其他 Ο(nlogn) 算法更快,因为它的内部循环(inner loop)可以在大部分的架构上很有效率地被实现出来。
