Bubble Sort es el algoritmo de clasificación más simple que funciona intercambiando repetidamente los elementos adyacentes si están en el orden incorrecto. Este algoritmo no es adecuado para grandes conjuntos de datos, ya que su complejidad de tiempo promedio y en el peor de los casos es bastante alta.
¿Cómo funciona la clasificación por burbujas?
Considere una array arr[] = {5, 1, 4, 2, 8}
C++
// C++ program for implementation

#include <bits/stdc++.h>
using namespace std;
// A function to implement bubble sort

{
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[] = { 5, 1, 4, 2, 8};
int N = sizeof(arr) / sizeof(arr[0]);
bubbleSort(arr, N);
cout << "Sorted array: \n";
printArray(arr, N);
return 0;
