The simplistic multiplication method for the HumonguousInteger class from Exercise 17 is not efficient. A more complicated, but much faster approach is to implement the long multiplication technique we learned in elementary school. Implement the multiplication method by using the long multiplication technique.
Exercise 17
Implement a simplistic multiplication solution for the HumongousInteger class. We can compute the product of two humongous integers L and R by adding L to the result R times. For example, to derive the product of 8 and 3, we compute
Test the multiplication operation with the testing pattern used in Section 16.5. But decrease the magnitude of the values we use, for example,
Since the simplistic multiplication algorithm results in a very long execution time, we do not want to test it with large values.
