$(5$ marks$)Al$ and Bill are arguing about the performance of their sorting algorithms. Al claims that his $O(NlogN)-$time algorithm is always faster than Bill's $O(N^2)-$time algorithm, where $N$ is the input size. To settle the issue, they implement and run the two algorithms on many randomly generated data sets. To Al's dismay, they find that if $N<mn\; id="EditorElement\_1385887">1</mn><mn\; id="EditorElement\_1385888">0</mn><mn\; id="EditorElement\_1385889">0</mn>$ the $O(N^2)-$time algorithm actually runs faster, and only when $N100$ the $O(NlogN)-$time one is better. Explain why the above scenario is possible. Give numerical examples.
