Objectives
Implement a bubblesort recursively
import java.util.Arrays; public class Main{ public static void main(String[] args) { int arr[] = {9,4,1,5,2,8}; System.out.print("Before sorting: "); printArray(arr); bubbleSort(arr, arr.length); System.out.print("After sorting: "); printArray(arr); } static void printArray(int arr[]){ for(int i = 0; i < arr.length; i++){ System.out.print(arr[i] + " "); } System.out.println(); } static void bubbleSort(int arr[], int size){ // base case - the recursive calls has reached the last element to be checked // recursive step - a single pass of the bubblesort algorithm // call the next step } }
