1. Write a program to demonstrate mergeSort in the class StringSorter, as given. Model your program after the one given for a selection sort of integers.

2. If n is a positive integer in Java, n%b is the rightmost digit in the base b representation of n. Moreover, n/b is the value of the integer after dropping the rightmost digit of n. Write a recursive method that displays a positive integer in a given base between 2 and 10.
