// utility.cpp

// IN THIS FILE, define any of your OWN functions you may need to 
// solve the problems.    

// For example, if you need an isPrime function, you can put the function
// definition in this file.  Similarly, isOdd or isEven might be useful.

// You will need to include the function prototype in "utility.h" and
// then be sure to  #include "utility.h" in the file where you use
// these functions
