 * FizzBuzz: From 1 to 100, print "Fizz" if divisible by 3, "Buzz" if divisible
 * by 5, "FizzBuzz" if divisible by both, and the number itself otherwise

 * I did this basic but interesting exercise in the Madrid 42 entrance exams and
 I thought it would be interesting to be able to transfer it to the Java language
