This iteration repeates for n 1 timessteps where n is the number of elements in the list.
The distance and direction that elements must move during the sort determine bubble sort s performance because elements move in different directions at different speeds. After each iteration, one less element the last one is needed to be compared until there are no more elements left to be compared. In the case of nearly sorted data, bubble sort takes on time, but requires at least 2 passes through the data whereas insertion sort requires something more like 1 pass.

Starting from the beginning of the list, compare every adjacent pair, swap their position if they are not in the right order the latter one is smaller than the former one. In selection sort, we start with the positions in the array and select the correct elements to fill them. In this algorithm each iteration removes an element from the input data and inserts it into the correct position in the list being sorted. The bubble sort was originally written to bubble up the highest element in.
