//! Exercise 9.45:
//! Write a funtion 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.
//!

//! @output :
//Mr. alan Jr.
//Mr. alan Jr.
//Mr. alan Jr.
//Mr. alan Jr.

Based on @queequeg's implementation

so beautiful! 👍
