冒泡排序-Python与PHP实现版

Python实现

import random

a=[random.randint(1,999) for x in range(0,33)]

# 冒泡排序,python中数组是按引用传递的，会直接在原数组上修改
def bubbleSort(array):
    flag = True
    i=0

    while i<len(array) and flag:
        j=len(array)-1
　　　　　flag = False

        while j>i:
            if array[j-1] > array[j]:
                array[j-1],array[j] = array[j],array[j-1]
                flag = True
            j=j-1

        i = i + 1

bubbleSort(a)
print(a)

PHP实现

<?php
$a = [];

for($i=0;$i<36;$i++){
    array_push($a,mt_rand(1,999));
}
shuffle($a);

function bubbleSort(&$a){
    $flag = true;

    for($i = 0;$i<count($a) && $flag;$i++){
        $flag = false;

        for($j = count($a)-1;$j>$i;$j--){
            if($a[$j-1] > $a[$j]){
                $a[$j] += $a[$j-1];
                $a[$j-1] = $a[$j]-$a[$j-1];
                $a[$j] -= $a[$j-1];
                $flag = true;
            }
        }

    }
}

bubbleSort($a);
