Bubble sort algorithm code example

Example 1: bubble sort python

def bubbleSort(lis):
    length = len(lis)
    for i in range(length):
        for j in range(length - i):
            a = lis[j]
            if a != lis[-1]:
                b = lis[j + 1]
                if a > b:
                    lis[j] = b
                    lis[j + 1] = a
    return lis

Example 2: bubble sort in java

public static void bubbleSort(int arr[])
{
	for (int i = 0; i < arr.length; i++) //number of passes
    {
		//keeps track of positions per pass      
    	for (int j = 0; j < (arr.length - 1 - i); j++) //Think you can add a -i to remove uneeded comparisons 
        {
          	//if left value is great than right value 
        	if (arr[j] > arr[j + 1])
            {
              	//swap values
            	int temp = arr[j];
              	arr[j] = arr[j + 1];
              	arr[j + 1] = temp; 
            }
        }
    }
}

Example 3: interchange sort in system programming

#include<stdio.h>
void BubbleSort(int arr[],int len){
    for(int j = 0 ; j < len-1 ; j ++){
        for(int i = 0; i < len-1 ; i++){
            if(arr[i] > arr[i+1]){
                int temp = arr[i+1];
                arr[i+1] = arr[i];
                arr[i] = temp;
            }
        }
    
    }
    printf("\nBubble Sorted Array : ");
    for(int i = 0; i < len ; i++){
           printf(" %d",arr[i]); 
        }
}
int main(){ 
    printf("Please Enter Size of Array you want to Sort \n > ");
    int len; 
    scanf("%d",&len);
    int arr[len] ;
    for(int i = 0 ; i < len ; i++){
        printf("\n Please Enter %d number of Element of Array \n",i);
        scanf("%d",&arr[i]);
    }
    BubbleSort(arr,len);
    return 0;
}

Example 4: bubble sort code

func Sort(arr []int) []int {
	for i := 0; i < len(arr)-1; i++ {
		for j := 0; j < len(arr)-i-1; j++ {
			if arr[j] > arr[j+1] {
				temp := arr[j]
				arr[j] = arr[j+1]
				arr[j+1] = temp
			}
		}
	}
	return arr
}

Example 5: Write a program to sort an array 100,200,20, 75,89.198, 345,56,34,35 using Bubble Sort. The program should be able to display total number of passes used for sorted data in given data set.

void swap(int *xp, int *yp) 
{ 
    int temp = *xp; 
    *xp = *yp; 
    *yp = temp; 
} 
  
// An optimized version of Bubble Sort 
void bubbleSort(int arr[], int n) 
{ 
   int i, j; 
   bool swapped; 
   for (i = 0; i < n-1; i++) 
   { 
     swapped = false; 
     for (j = 0; j < n-i-1; j++) 
     { 
        if (arr[j] > arr[j+1]) 
        { 
           swap(&arr[j], &arr[j+1]); 
           swapped = true; 
        } 
     } 
  
     // IF no two elements were swapped by inner loop, then break 
     if (swapped == false) 
        break; 
   } 
}

Example 6: bubble sort algorithm

#include <bits/stdc++.h>

using namespace std;

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

int main(){
    int arr[] = {1,7,33,9,444,2,6,33,69,77,22,9,3,11,5,2,77,3};
    int n = sizeof(arr) / sizeof(arr[0]);

    bubbleSort(arr, n);

    for(int i=0;i<n;i++){
        cout << arr[i] << " ";
    }

    return 0;
