现有数十个网络接口(网络接口由 eth+数字编号组成),如 eth0,eth1,eth2,..eth12 等,请将乱序的网络 接口排序,由 n 表示数字编码,n 的范围 0<n<50。请用C语言使用三种方法实现

1. 冒泡排序
```c
#include <stdio.h>
void bubble_sort(int arr[], int n) {
int i, j, temp;
for (i = 0; i < n - 1; i++) {
for (j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
}
int main() {
int arr[] = { 12, 3, 5, 7, 1, 9, 2, 4, 6, 8, 10, 11 };
int n = sizeof(arr) / sizeof(arr[0]);
bubble_sort(arr, n);
for (int i = 0; i < n; i++) {
printf("eth%d ", arr[i]);
}
return 0;
}
```
2. 插入排序
```c
#include <stdio.h>
void insertion_sort(int arr[], int n) {
int i, j, key;
for (i = 1; i < n; i++) {
key = arr[i];
j = i - 1;
while (j >= 0 && arr[j] > key) {
arr[j + 1] = arr[j];
j--;
}
arr[j + 1] = key;
}
}
int main() {
int arr[] = { 12, 3, 5, 7, 1, 9, 2, 4, 6, 8, 10, 11 };
int n = sizeof(arr) / sizeof(arr[0]);
insertion_sort(arr, n);
for (int i = 0; i < n; i++) {
printf("eth%d ", arr[i]);
}
return 0;
}
```
3. 快速排序
```c
#include <stdio.h>
void swap(int* a, int* b) {
int temp = *a;
*a = *b;
*b = temp;
}
int partition(int arr[], int low, int high) {
int pivot = arr[high];
int i = low - 1;
for (int j = low; j <= high - 1; j++) {
if (arr[j] < pivot) {
i++;
swap(&arr[i], &arr[j]);
}
}
swap(&arr[i + 1], &arr[high]);
return (i + 1);
}
void quick_sort(int arr[], int low, int high) {
if (low < high) {
int pi = partition(arr, low, high);
quick_sort(arr, low, pi - 1);
quick_sort(arr, pi + 1, high);
}
}
int main() {
int arr[] = { 12, 3, 5, 7, 1, 9, 2, 4, 6, 8, 10, 11 };
int n = sizeof(arr) / sizeof(arr[0]);
quick_sort(arr, 0, n - 1);
for (int i = 0; i < n; i++) {
