用c语言编写冒泡法和快速排序法对给定序列排序的程序（递归非递归两种方法）

冒泡排序法（非递归）：

#include <stdio.h>

void bubbleSort(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[] = { 64, 34, 25, 12, 22, 11, 90 };
    int n = sizeof(arr) / sizeof(arr[0]);
    bubbleSort(arr, n);
    printf("Sorted array: \n");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

冒泡排序法（递归）：

#include <stdio.h>

void bubbleSortRecursive(int arr[], int n) {
    if (n == 1) {
        return;
    }
    int i, temp;
    for (i = 0; i < n - 1; i++) {
        if (arr[i] > arr[i + 1]) {
            temp = arr[i];
            arr[i] = arr[i + 1];
            arr[i + 1] = temp;
        }
    }
    bubbleSortRecursive(arr, n - 1);
}

int main() {
    int arr[] = { 64, 34, 25, 12, 22, 11, 90 };
    int n = sizeof(arr) / sizeof(arr[0]);
    bubbleSortRecursive(arr, n);
    printf("Sorted array: \n");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

快速排序法（非递归）：

#include <stdio.h>

void swap(int* a, int* b) {
    int t = *a;
    *a = *b;
    *b = t;
}

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 quickSort(int arr[], int low, int high) {
    int stack[high - low + 1];
    int top = -1;
    stack[++top] = low;
    stack[++top] = high;
    while (top >= 0) {
        high = stack[top--];
        low = stack[top--];
        int pi = partition(arr, low, high);
        if (pi - 1 > low) {
            stack[++top] = low;
            stack[++top] = pi - 1;
        }
        if (pi + 1 < high) {
            stack[++top] = pi + 1;
            stack[++top] = high;
        }
    }
}

int main() {
    int arr[] = { 64, 34, 25, 12, 22, 11, 90 };
    int n = sizeof(arr) / sizeof(arr[0]);
    quickSort(arr, 0, n - 1);
    printf("Sorted array: \n");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

    int t = *a;

        int pi = partition(arr, low, high);
        quickSort(arr, low, pi - 1);
        quickSort(arr, pi + 1, high);
    }
}

    int arr[] = { 64, 34, 25, 12, 22, 11, 90 };
    int n = sizeof(arr) / sizeof(arr[0]);
    quickSort(arr, 0, n - 1);
    printf("Sorted array: \n");

    }
    return 0;
