Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent pairs and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. Bubble sort is a comparison sort, i.e. it sorts only by comparing and swapping list elements. https://en.wikipedia.org/wiki/Bubble_sort
