C++ Program for the Recursive Bubble Sort?
In Bubble sort compares adjacent pairs and swaps them if they are in the wrong order. In this type of bubble sort we use the recursive function that calls itself.
Input:53421 Output:12345
Explanation
Use of recursive (self-calling) function compares adjacent pairs and swaps them if they are in the wrong order until the array is in order
Example
#include <iostream>
using namespace std;
void bubbleSort(int arr[], int n) {
for (int i = 0; i < n - 1; i++) {
if (arr[i] > arr[i + 1]) {
int temp = arr[i];
arr[i] = arr[i+1];
arr[i+1] = temp;
}
}
if (n - 1 > 1) {
bubbleSort(arr, n - 1);
}
}
int main() {
int arr[] = { 5,4,2,1,3 };
int n = 5;
bubbleSort(arr, n);
for (int i = 0; i < n; i++) {
cout<< arr[i]<<"\t";
}
return 0;
}
