An array is nearly-d sorted if any element is not further than d spots from its sorted position.
Consider the sorted list of elements:
X = [1,5, 9, 10, 15, 20, 34, 57, 66, 91]
The same elements form a nearly-sorted list:
A = [1,5, 10, 15, 9, 20, 34, 57, 91, 66]
with d = 2 because each value is, at most, 2 spots from its sorted position. Consider that the value
9 is out of order as it is in index 42 in A while it is in index 2 in B. Similarly,
B = [1,5, 10, 9, 15, 20, 34, 57, 91, 66]
is nearly sorted with d = 1 as value 9 is in index 3 instead of index 2, 66 is in index 9 instead of
index 8 and so on.
Bubble Sort3, a sorting algorithm we have not covered, has an advantage over other methods
when operating on nearly-d sorted lists.
