During the scan, we compare the i th element with the i+1 th element (i.e. the element next to it). If i th element is greater than its next element, then we swap them (swapping takes constant time, not linear).

Web6 okt. 2024 · Bubble sort halts after a pass in which no swaps were made. As is evident, if bubble sort halts after one pass, then the array must have been sorted. When does bubble sort halt after two passes? If after the first pass, the array is sorted. In this case, if we know which swaps were made, then we can recover the input permutation. Furthermore ... WebA user on stackoverflow did a simpler experiment which suggests that the number of swaps is the same in bubble sort and inversion sort (at least for the user's version of these algorithms, quoted in the question). This would imply, of course, that the average number of swaps is the same in both algorithms. WebQ.
