/**
 * Exercise 9.45: Write a function that takes a string representing a name
 * and two other strings representing a prefix, such as “Mr.” or “Ms.” and a
 * suffix, such as “Jr.” or “III”. Using iterators and the insert and append
 * functions, generate and return a new string with the suffix and prefix
 * added to the given name.
 *
 * Exercise 9.46: Rewrite the previous exercise using a position and length to
 * manage the strings. This time use only the insert function.
