bubble search code example

Example 1: bubble sort in java

public static void bubbleSort(int arr[])
{
	for (int i = 0; i < arr.length; i++) //number of passes
    {
		//keeps track of positions per pass      
    	for (int j = 0; j < (arr.length - 1 - i); j++) //Think you can add a -i to remove uneeded comparisons 
        {
          	//if left value is great than right value 
        	if (arr[j] > arr[j + 1])
            {
              	//swap values
            	int temp = arr[j];
              	arr[j] = arr[j + 1];
              	arr[j + 1] = temp; 
            }
        }
    }
}

Example 2: Write a program to sort an array 100,200,20, 75,89.198, 345,56,34,35 using Bubble Sort. The program should be able to display total number of passes used for sorted data in given data set.

void swap(int *xp, int *yp) 
{ 
    int temp = *xp; 
    *xp = *yp; 
    *yp = temp; 
} 
  
// An optimized version of Bubble Sort 
void bubbleSort(int arr[], int n) 
{ 
   int i, j; 
   bool swapped; 
   for (i = 0; i < n-1; i++) 
   { 
     swapped = false; 
     for (j = 0; j < n-i-1; j++) 
     { 
        if (arr[j] > arr[j+1]) 
        { 
           swap(&arr[j], &arr[j+1]); 
           swapped = true; 
        } 
     } 
  
     // IF no two elements were swapped by inner loop, then break 
     if (swapped == false) 
        break; 
   } 
}
