Choose The Correct Function For Recursive Bubble Sort #1017

 void rec_bubbleSort(int arr[], int n) { if (n == 1) return; for (int i=0; i<n-1; i++) if (arr[i] > arr[i+1]) { swap(arr[i], arr[i+1]); } rec_bubbleSort(arr, n-1); } 

 void rec_bubbleSort(int arr[], int n) { if (n == 2) return; for (int i=0; i<n-1; i++) if (arr[i] > arr[i+1]) { swap(arr[i], arr[i+1]); } rec_bubbleSort(arr, n-1); } 

 void rec_bubbleSort(int arr[], int n) { if (n == 1) return; for (int i=0; i<n-1; i++) if (arr[i] < arr[i+1]) { swap(arr[i], arr[i+1]); }  rec_bubbleSort(arr, n-1); } 

 void rec_bubbleSort(int arr[], int n) { if (n == 2) return; for (int i=0; i<n-1; i++) if (arr[i] < arr[i+1]) { swap(arr[i], arr[i+1]); }  rec_bubbleSort(arr, n-1); }
