冒泡排序是一种简单的排序算法。它重复地走访过要排序的数列,一次比较两个元素,如果他们的顺序错误就把他们交换过来。走访数列的工作是重复地进行直到没有再需要交换,也就是说该数列已经排序完成。这个算法的名字由来是因为越小的元素会经由交换慢慢“浮”到数列的顶端。
算法描述
- 比较相邻的元素。如果第一个比第二个大,就交换他们两个。
- 对每一对相邻元素作同样的工作,从开始第一对到结尾的最后一对。这步做完后,最后的元素会是最大的数。
- 针对所有的元素重复以上的步骤,除了最后一个。
- 持续每次对越来越少的元素重复上面的步骤,直到没有任何一对数字需要比较。
示例代码
C
#include <stdio.h>
void bubble_sort(int arr[], int len) {
int i, j, temp;
for (i = 0; i < len - 1; i++)
for (j = 0; j < len - 1 - i; j++)
if (arr[j] > arr[j + 1]) {
temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
int main() {
int arr[] = { 22, 34, 3, 32, 82, 55, 89, 50, 37, 5, 64, 35, 9, 70 };
int len = (int) sizeof(arr) / sizeof(*arr);
bubble_sort(arr, len);

for (i = 0; i < len; i++)
