Recursive Bubble Sort

Bubble sort is a simple sorting algorithm that repeatedly steps through the list to be sorted, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted.

Recursive bubble sort is a variant of the bubble sort algorithm that employs recursion to perform the sort. In recursive bubble sort, instead of using nested loops to compare adjacent elements and swap them, the function calls itself recursively with a modified input list after each pass.

In each recursive call, the function compares adjacent elements and swaps them if necessary, and then passes the modified list to the next recursive call. The recursion continues until the list is sorted.

Recursive bubble sort has the same time complexity as the regular bubble sort, which is O(n^2). However, recursive bubble sort uses more memory because it creates new copies of the list for each recursive call.

Program Solution

//C Program
//Recursive Bubble Sort
#include <stdio.h>

//Display array elements
void display(int record[], int size)
{
	for (int i = 0; i < size; ++i)
	{
		printf("%d ", record[i]);
	}
	printf("\n");
}
//Perform bubble sort in given array
void bubble_sort(int record[], int size)
{
	if (size <= 0)
	{
		//When have no more than one element
		return;
	}
	int temp = 0;
	for (int i = 0; i < size - 1; ++i)
	{
		//Compare two adjacent elements
		if (record[i] > record[i + 1])
		{
			//When need to swap two adjacent elements
			temp = record[i];
			record[i] = record[i + 1];
			record[i + 1] = temp;
		}
	}
	bubble_sort(record, size - 1);
}
int main()
{
	//Assume given array elements
	int record[] = {
		2 , 8 , 1 , 5 , 0 , 9 , 3 , 7 , 2
	};
	//Get the size of array 
	int size = sizeof(record) / sizeof(record[0]);
	//Before sort
	display(record, size);
	bubble_sort(record, size);
	//After sort
	display(record, size);
	return 0;
}
