bubble sort explained code example

Example 1: bubble sort c

#include <bits/stdc++.h> 
using namespace std; 
  
void swap(int *xp, int *yp)  
{  
    int temp = *xp;  
    *xp = *yp;  
    *yp = temp;  
}  
  
// A function to implement bubble sort  
void bubbleSort(int arr[], int n)  
{  
    int i, j;  
    for (i = 0; i < n-1; i++)      
      
    // Last i elements are already in place  
    for (j = 0; j < n-i-1; j++)  
        if (arr[j] > arr[j+1])  
            swap(&arr[j], &arr[j+1]);  
}  
  
/* Function to print an array */
void printArray(int arr[], int size)  
{  
    int i;  
    for (i = 0; i < size; i++)  
        cout << arr[i] << " ";  
    cout << endl;  
}  
  
// Driver code  
int main()  
{  
    int arr[] = {64, 34, 25, 12, 22, 11, 90};  
    int n = sizeof(arr)/sizeof(arr[0]);  
    bubbleSort(arr, n);  
    cout<<"Sorted array: \n";  
    printArray(arr, n);  
    return 0;  
}

Example 2: 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 3: 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;

}

Example 4: bubble sort

/*bubble sort;timecomplexity=O(n){best case}
               time complexity=O(n^2){worst case}
               space complexity=O(n);auxiliary space commplexity=O(1)

Example 5: bubble sort integers

for (int i = 0; i < n-1; i++) 
            for (int j = 0; j < n-i-1; j++) 
                if (arr[j] > arr[j+1]) 
                { 
                    // swap arr[j+1] and arr[i] 
                    int temp = arr[j]; 
                    arr[j] = arr[j+1]; 
                    arr[j+1] = temp; 
                }
