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).
