Comparison of Java and Python3 bubble sorting

Bubble sorting can be said to be one of the most entry-level algorithms among sorting algorithms. Because it is simple and easy to understand, it is often used as an introductory algorithm for sorting in the classroom.

Bubble sorting is a well-known business, and its sorting process is like bubbles in water, ascending from bottom to top. The figure below shows the bubble sorting process: Assume that the sequence to be sorted is {10, 2, 11, 8, 7}.

#Java

 1 package com.algorithm.sort.bubble; 2  3 import java.util.Arrays; 4  5 /** 6  * 冒泡排序 7  * Created by yulinfeng on 6/19/17. 8  */ 9 public class Bubble {10     public static void main(String[] args) {11         int[] nums = {10, 2, 11, 8, 7};12         nums = bubbleSort(nums);13         System.out.println(Arrays.toString(nums));14     }15 16     /**17      * 冒泡排序18      * @param nums 待排序数字序列19      * @return 排好序的数字序列20      */21     private static int[] bubbleSort(int[] nums) {22 23         for (int i = 0; i  nums[j + 1]) {26                     int temp = nums[j];27                     nums[j] = nums[j + 1];28                     nums[j + 1] = temp;29                 }30             }31         }32 33         return nums;34     }35 }

Python3

 1 #冒泡排序 2 def bubble_sort(nums): 3     for i in range(len(nums)): 4         for j in range(len(nums) - i - 1): 5             if nums[j] > nums[j + 1]: 6                 temp = nums[j] 7                 nums[j] = nums[j + 1] 8                 nums[j + 1] = temp 9     10     return nums11 12 nums = [10, 2, 11, 8, 7]13 nums = bubble_sort(nums)14 print(nums)
