写一个冒泡排序，用5种不同的语言

好的，以下是五种不同语言实现的冒泡排序代码：

Python 3:

def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n-i-1):
            if arr[j] > arr[j+1] :
                arr[j], arr[j+1] = arr[j+1], arr[j]

arr = [64, 34, 25, 12, 22, 11, 90]
bubble_sort(arr)
print("Sorted array is:", arr)

Java:

public static void bubbleSort(int[] arr) {
    int n = arr.length;
    for (int i = 0; i < n-1; i++)
        for (int j = 0; j < n-i-1; j++)
            if (arr[j] > arr[j+1])
            {
                int temp = arr[j];
                arr[j] = arr[j+1];
                arr[j+1] = temp;
            }
}

int arr[] = {64, 34, 25, 12, 22, 11, 90};
bubbleSort(arr);
System.out.println("Sorted array is: ");
for (int i=0; i<arr.length; ++i)
    System.out.print(arr[i] + " ");

C++:

void bubbleSort(int arr[], int n) {
    int i, j;
    for (i = 0; i < n-1; i++)
        for (j = 0; j < n-i-1; j++)
            if (arr[j] > arr[j+1])
                swap(arr[j], arr[j+1]);
}

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

JavaScript:

function bubbleSort(arr) {
    var i, j;
    for (i = 0; i < arr.length-1; i++)
        for (j = 0; j < arr.length-i-1; j++)
            if (arr[j] > arr[j+1]) {
                var temp = arr[j];
                arr[j] = arr[j+1];
                arr[j+1] = temp;
            }
}

var arr = [64, 34, 25, 12, 22, 11, 90];
bubbleSort(arr);
console.log("Sorted array is: " + arr);

PHP:

function bubbleSort(&$arr) {
    $n = count($arr);
    for($i = 0; $i < $n; $i++) {
        for($j = 0; $j < $n - $i - 1; $j++) {
            if($arr[$j] > $arr[$j+1]) {
                $temp = $arr[$j+1];
                $arr[$j+1] = $arr[$j];
                $arr[$j] = $temp;
            }
        }
    }
}

$arr = array(64, 34, 25, 12, 22, 11, 90);
bubbleSort($arr);
echo "Sorted array is: ";
for($i = 0; $i < count($arr); $i++) {
    echo $arr[$i]." ";
}

以上是五种不同语言实现的冒泡排序代码，希望能对您有所帮助。
