Exchange Sort (Bubble sort)
•Notice that the list is not sorted after this first pass.
–We have just "bubbled" the largest element up to its proper position at the end of the list!
–During the second pass, you do the exact same thing....but excluding the largest (last) element in the array since it should already be in sorted order.
–After the second pass, the second largest element in the array will be in its proper position (next to the last position).
