用c语言写一个双向冒泡排序

以下是C语言实现双向冒泡排序的代码：

#include <stdio.h>

void bubbleSort(int arr[], int n) {
    int left = 0, right = n - 1;
    while (left < right) {
        for (int i = left; i < right; i++) {
            if (arr[i] > arr[i + 1]) {
                int temp = arr[i];
                arr[i] = arr[i + 1];
                arr[i + 1] = temp;
            }
        }
        right--;
        for (int i = right; i > left; i--) {
            if (arr[i] < arr[i - 1]) {
                int temp = arr[i];
                arr[i] = arr[i - 1];
                arr[i - 1] = temp;
            }
        }
        left++;
    }
}

int main() {
    int arr[] = {5, 2, 8, 4, 9, 1, 6, 3, 7};
    int n = sizeof(arr) / sizeof(arr[0]);
    bubbleSort(arr, n);
    printf("Sorted array: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}
