4 0

Answer:

quicksort

Explanation:

There are many types of asymptotically efficient sorting algorithms that can be used but one of the more commonly used for large data lists would be quicksort. This is a sorting algorithm that focuses on choosing a value from the list and working around that value in order to sort the data piece by piece. For larger data sets this method is widely used due to its speed and efficiency which is exactly what Martha needs in this scenario.
