This algorithm is named as bubble sort because, same as like bubbles the smaller or lighter elements comes up at start and bigger or heavier elements goes down at end.
The bubble sort algorithm isnt efficient as its averagecase complexity is o n 2 and worstcase complexity is o n 2. Although the algorithm is simple, most of the other sorting algorithms are more efficient for large lists. You will also need to decide on a separator you want to use or else all the integers will be written side by side preventing the reader from making sense of them.
