Quick FizzBuzz implementations

// corrected from initial approach, using % 15. My first attempt was wrong. This is what I get for not writing tests. Although tests on println...hmm...

    else if (x % 3 == 0) println "Fizz"
    else if (x % 5 == 0) println "Buzz"
    else println x

// groovier with the range, and optimizing if modulo was expensive

    StringBuilder sb = new StringBuilder()
    if (x % 3 == 0) sb.append("Fizz")
    if (x % 5 == 0) sb.append("Buzz")
