Expert Solution

solution:

I would suggest you to go with B-Tree or Red-Black Tree or AVL Tree.
The average access time for all the above data structures is theta(log n)
The worst case access time is also O(log n).

Not only access but also search, insertion, deletion is also same in both the cases.

Recall that Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Now suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer file....
