Al and Bob are arguing about their algorithms. Al claims his O(n logn)-time method is always faster than Bob's O(n2)-time method. To settle the issue, they perform a set of experiments. To Al's dismay, they find that if n< 100, the O(n²)-time algorithm runs faster, and only when n> 100 is the O(nlogn)-time one better. Explain how this is possible.

one better. Explain how this is possible.
