Making statements based on opinion; back them up with references or personal experience. each element "moves" closer to its final position at a rate of 1 swap per pass is incorrect. Compare the first value in the list with the next one up. The bubble sorting algorithm's a type of comparison sort, and its name refers to how larger items "bubble" to the top of the data set. Bubble Sort - javatpoint So it's somewhere in between. You can make a tax-deductible donation here. For the list of items in an array i.e. Just like the way bubbles rise from the bottom of a glass, bubble sort is a simple algorithm that sorts a list, allowing either lower or higher values to bubble up to the top. As 4 < 6, these are already in order, and the algorithm moves on: The next two values are also swapped because 3 < 6: The last two values, 6 and 9, are already in order, so the algorithm does not swap them. For a detailed analysis of bubble sort, see The Art of Computer Programming Volume 3: Sorting and Searching section 5.2.2. As with a bubble sort, after the first pass, the largest item is in the correct place. The time it takes to sort input numbers increases exponentially. Since only 5 elements of an array needed to be sorted, it took only 3 iterations. The array is sorted when L(i) = 0 for all i. Bubble sort: how to calculate amount of comparisons and swaps In the book, what I called the L(i) function is called the inversion table of the array.

The bubble sort algorithm is a reliable sorting algorithm. when it is not the best case (no of passes is 1 for a sorted array), No. In your example: The max L(i) is L(2): the element at index 2 is 8 and there are two elements left of 8 that are larger than 8. Sort It compares the next two values, 4 and 6. As said by others, the number of passes equals the amplitude of the largest element displacement required. The displacement is the difference betwe Sort Please refresh the page or try after some time. After public class BubbleSortExample { static void bubbleSort (int[] arr) { Why can't the change in a crystal structure be due to the rotation of octahedra? Here the number of passes are (n-2). If current element is greater than the next element, it is swapped. iteration - No of Passes in a Bubble Sort - Stack Overflow This shifting of elements is done until all the digits are completely sorted in the required order. I believe the number of swaps performed is sum(L(i)) for the definition of L given in my answer. When a gnoll vampire assumes its hyena form, do its HP change? Sorting is done recursively comparing the adjacent numbers and shifting them in the increasing or decreasing order. Let us understand the bubble sort algorithm by taking an example. Therefore the number of passes required is max(L(0), L(1), , L(n-1)).
